The "amplc_pci230" driver currently retains the legacy attach mechanism
to allow devices to be attached manually via the `COMEDI_DEVCONFIG`
ioctl.  The only real use for this is to pretend that a PCI230+ or
PCI260+ is a PCI230 or PCI260 for backwards compatibility, as they have
different number of bits of resolution on the AI subdevice.  Since the
card would be automatically configured as a PCI230+ or PCI260+ at PCI
probe time anyway, hopefully any users who want it to appear as a PCI230
or PCI260 would have got tired of removing the automatically configured
device and configuring it manually by now and will have updated their
software to cope with the PCI230+ or PCI260+.

Get rid of the legacy attach mechanism by removing the Comedi driver
"attach" handler `pci230_attach()` and associated code.  Also remove the
"wildcard" entry from the board table `pci230_boards[]` as it is no
longer needed.  Don't bother initializing the `board_name`, `offset`,
and `num_names` members of `struct comedi_driver amplc_pci230_driver`
any longer as they are only needed when configuring the device manually.

Pull Xtensa updates from Chris Zankel:
 "Xtensa improvements for 3.17:
   - support highmem on cores with aliasing data cache.  Enable highmem
     on kc705 by default
   - simplify addition of new core variants (no need to modify Kconfig /
     Makefiles)
   - improve robustness of unaligned access handler and its interaction
     with window overflow/underflow exception handlers
   - deprecate atomic and spill registers syscalls
   - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
     statements
   - wire up renameat2 syscall.

  Various fixes:
   - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
   - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
   - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
     (runtime unrecoverable exception)
   - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
     register clobbering)
   - fix kernel/user jump out of fast_unaligned (potential runtime
     unrecoverabl exception)
   - replace termios IOCTL code definitions with constants (userspace
     build breakage)"
