The board supported by this driver always has a digital input subdevice.
Remove the boardinfo for it and just open-code the relevant data in the
subdevice init.

Remove the SDF_GROUND and SDF_COMMON from the subdevice 'subdev_flags'.
These flags only have meaning for analog input/output subdevices.

Remove the subdevice 'len_chanlist' initialization. This variable only
has meaning for subdevices that support asynchronous commands.

Remove the subdevice 'io_bits' initialization. Digital input subdevices
don't use this variable.

Remove the subdevice function pointers that evaluate to NULL based on the
boardinfo data.

Move the apci2200_di_insn_bits() function from the hwdrv_apci2200.c file
into the main driver file.

For aesthetic reasons, rename the #define used for the register used to
read the digital inputs.

This driver is for a simple 16 channel digital output (relays), 8 channel
digital input board. Using the addi-data "common" code introduces a lot
of bloat.

Copy the code in addi_common.c to this driver and remove the #include
that caused addi_common.c to be compiled with this driver. This will
allow removing the bloat.

associated with this driver.

been there since pre-Android 1.0.  Those apis are not exposed to
Android apps, I don't see any problem deleting them."

Thus this patch removes the ANDROID_ALARM_SET_OLD and
ANDROID_ALARM_SET_AND_WAIT_OLD ioctl compatability
logic.
