McSPI functional updates:

 - Implement the spi_transfer.delay_usecs mechanism (previously omitted).

 - Remove strange per-device <asm/arch/mcspi.h> hookery ... it's not even
   correct as a per-device config.  We *always* want "single channel" mode
   (in "keep chipselect active" mode); and if we used "turbo", it would
   be a per-transfer option (as an rx-only double buffering tweak).

 - When enabling/disabling a channel, old value is irrelevant; don't read.

 - Sanity check spi->mode bits, and reject ones we don't support.

 - Streamline DMA channel selection:  do it once during probe(), using static
   tables; smaller, faster.  OMAP 2430 still needs changes here, minimally for
   the third SPI controller.  (Board init should change too, to not assume
   all SPI controllers are used on every board...)

 - Remove #ifdefs around doing reset on driver startup ... enable clocks
   so we can do that (!), and turn on auto-idle.

 - Waste less time enabling/disabling the clocks while working the queue.

 - Flag DMA channels as freed when we do so ... so they can't get reused
   later (when another driver may own them).

 - Minor PIO fix: don't need to verify TX side completed except for TX_ONLY
   mode, since RX completed implies TX completed.

 - Remove bogus code which always dropped chipselect after the last RX_ONLY
   word (rather than leaving it enabled).

 - Move error checks out of work loop into setup() and transfer(), so that
   they're reported ASAP rather than as mysterious transfer errors).

Plus a handful of cleanups:  whitespace fixes, comments.

Initial updates for McSPI driver:

 - bug fixes:
    * handle byte-wide tx pio correctly for multiple bytes
    * cleanup workqueue on module exit
    * allow modular build (and rmmod)
    * request_mem_region
    * remove wrongly exported driver symbol

 - cleanup:
    * remove needless debug strings from object file
    * remove needless init and exit sections from object file
    * remove superfluous get/put of spi_master
    * fix whitespace and indentation bugs
    * fix line-too-long bugs
    * use spi_master_*() calls not class_*() calls
    * use dev_*() messaging not printk

Combined with the next patch, this gives around a 10% shrink to the driver
footprint, improves correctness, and helps it get ready to merge upstream.

Various fixes needed to build the tsc2102 audio.  Several fixes
relate specifically to building it as a module.

Note that this doesn't address the need for omap-alsa-dma.c
to go into a separate module so that e.g. tsc2101 and tsc2102
modules can both be built, or the assumption that the audio
is going out over McBSP not EAC.

Partial build fixes for tsc2101 audio.  It still won't link though,
it needs undefined omap_tsc2101_{read,write}() functions to access
chip registers ... and requires that e.g. tsc2102 audio isn't also
configured (they use the same exported McBSP DMA functions, which
likewise prevent use with EAC).

The OMAP SPI controller drivers handle SPI_CPHA incorrectly.
It should mean:

  CPHA=0 ... sample at leading edge of clock
  CPHA=1 ... sample at trailing edge of clock

This fixes them, and the protocol drivers which depended on the wrong
meaning.  Separate ads7846 and omap_uwire patches are going upstream,
already since those drivers were already pushed there.  The tsc2102
code already had this right ... strange.
