omap2_mcspi fixes + cleanups
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.

tsc2102-alsa build fixes
Various fixes needed to build the tsc2102 audio. Several fixes

fix SPI_CPHA related errors
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

Additional cleanup for debug boards on H2/P2/H3/H4: move the init
code that's not board-specific into a new file where it can be easily
shared between all the different boards (avoiding code duplication,
and making it easier to support more devices). Make H4 use that.
This should be easy to drop in to the OMAP1 boards using these debug

of the smc using the fpga (probably all boards could do that, if it's
necessary) and doesn't use the gpio mux or request APIs.

- expect gpmc_cs_set_timings() caller to have initialized sync vs async

So be a bit more careful about testing the flag by making sure to test
