The driver's COMEDI "auto-attach" handler `db2k_auto_attach()` calls
`db2k_find_boardinfo()` to find an element of our board information
array `db2k_boardtypes[]` that matches the probed PCI device.  The
driver's PCI device table matches several boards in the DaqBoard/2000
series that match a single PCI vendor and device ID combination.
`db2k_find_boardinfo()` uses the probed PCI device's subvendor and
subdevice IDs to find the matching board information, returning `NULL`
for no match.

Change the driver's PCI device table `db2k_pci_table[]` to match
supported PCI vendor, device, subvendor and subdevice IDs, and set the
`.driver_data` member of each element to the index of the matching
element of `db2k_boardtypes[]`.  That index gets passed through to the
COMEDI auto-attach handler `db2k_auto_attach()`.  Use it to index
directly into `db2k_boardtypes[]` instead of calling
`db2k_find_boardinfo()` to find the match.
Use array index designators in the initializer of `db2k_boardtypes[]`.
Use enumerated constants defined by new type `enum db2k_boardids` to
name the board type indices.

The `id` member of `struct db2k_boardtype` is no longer used, so remove
it.  Also remove the subdevice ID macros `DB2K_SUBSYSTEM_IDS2` and
`DB2K_SUBSYSTEM_IDS4` as the subdevice IDs are now specified as numbers
in the PCI device table.  Remove `db2k_find_boardinfo()` as it is no
longer used.

The driver supports DaqBoard/2000 and DaqBoard/2001. DaqBoard/2000 has 2
AO channels, but DaqBoard/2001 has 4 AO channels.  The driver currently
only supports 2 AO channels, but supporting 4 channels is just a case of
setting the `n_chan` member of the COMEDI subdevice to 4 instead of 2.

Add a new boolean flag member `has_2_ao` to `struct db2k_boardtype` to
be set to `true` if the board only has 2 AO channels.  Set this to
`true` in the element of `db2k_boardtypes[]` that corresponds to the
DaqBoard/2000.  Use it in `db2k_auto_attach()` to initialize the number
of AO channels to 2 or 4, as appropriate.

According to an old GPL'ed driver at
<ftp://ftp.mccdaq.com/downloads/iotech_software/DaqBoard_1000_2000_Series/Linux_driver_kernelv2.4.x/>,
The CPLD status register can be checked to make sure that it is ready to
accept the next 16-bit word of FPGA firmware data, but that doesn't work
on older versions of the CPLD, where a simple delay should be used
between successive writes.  The current version of the Comedi driver
just uses a delay between successive writes.  Change it to check for the
newer CPLD in the `daqboard2000_load_firmware()`, and change the
firmware word writing function `daqboard2000_write_cpld()` to wait for
the status bit (`DB2K_CPLD_STATUS_TXREADY`, previously called
`DB2K_CPLD_TXDONE`) to be set for newer CPLD, or just delay for older CPLD.
Return an error if it times out waiting for the status bit.

The wait for the `DB2K_CPLD_STATUS_TXREADY` status bit to be set is
performed by new function `daqboard2000_wait_cpld_txready()`, which
returns 0 if the status bit is set within 100 microseconds, or
`-ETIMEDOUT` if not.

According to an old, GPL'ed Linux driver at
<ftp://ftp.mccdaq.com/downloads/iotech_software/DaqBoard_1000_2000_Series/Linux_driver_kernelv2.4.x/>,
after programming the FPGA, the General Purpose Input (USERI) of the PLX
PCI-9080 should go high shortly after a valid FPGA bitstream has been
loaded.  Add a new function `daqboard2000_wait_fpga_programmed()` to
wait for that, performing up to 200 checks over a 20 ms period (this is
loosely based on `pollFPGADone()` in the above-mentioned old driver).
Return 0 if the FPGA appears to have loaded successfully, or
`-ETIMEDOUT` if it runs out of checks.  Call it from the firmware
loading callback `daqboard2000_load_firmware()` after writing the
firmware to the FPGA to check it is programmed successfully.

`daqboard2000_poll_cpld()` waits for a specified status bit in the CPLD
status register to be set, giving up after 50 tries over a period of
about 5 milliseconds.  It returns 1 if the status bit is set, otherwise
0.  It is only ever called to check the "INIT" status bit.  Replace it
with new function `daqboard2000_wait_cpld_init()`, which returns 0 if
the "INIT" status bit becomes set within 50 tries, or `-ETIMEDOUT` if
not set within 50 tries.  The firmware loading callback
`daqboard2000_load_firmware()` may return the error result from
`daqboard2000_wait_cpld_init()` if it has used up all its firmware
loading attempts and that was the last error.

Firmware files for DAQBoard/2000 have a header, which is skipped,
followed by a sequence of FPGA configuration bytes to be programmed in
pairs.  The FPGA configuration bytes start with the sequence 0xff, 0x20.

Make the firmware loading callback function
`daqboard2000_load_firmware()` return an error `-EINVAL` if the FPGA
start sequence is not found, or the remaining length is not a multiple
of 2.

The firmware loading callback tries to program the FPGA up to 3 times
until it succeeds or it has tried too many times.  Currently, it
searches for the FPGA start sequence in the firmware data each time
through the retry loop.  Change it to adjust the start position and
length before entering the loop.

The Daqboard/2000 uses a PLX PCI-9080 chip to interface with the PCI
bus.  The "daqboard2000" driver uses the PCI-9080 "CNTRL" register to
perform various tasks, but defines its own macros for the register
values.  Use the macros from "plx9080.h" instead.  The various functions
that change the CNTRL register just wiggle individual bits up and down,
but they ignore the current register value - the old macros defined the
full value to be written to the register.  Change them to read and
modify the register value.

Also remove a read of the CNTRL register in `daqboard2000_auto_attach()`
where the value is just thrown away, as it seems to serve no purpose
there (such as flushing PCI writes).
