OMAP2430 builds/boots ok for me, but as Khem just pointed out,
OMAP1 builds are broken.

This patch gets OMAP1 building again:

init code depending on the CPU type.)

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.

Fixes some Kconfig glitches with lcd_mipid.c ... I suspect this

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.
