ARM: OMAP: abstract debug card setup (smc, leds)
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
cards; the only difference seems to be that the p2 does an extra reset
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.

GPMC updates:
- bugfixes: wrong/missing flags, omitted write, wrong test
- don't map memory segments starting at zero
- improve debug messaging
- export gpmc_get_fclk_perio]d() since it's needed to calc timings
- expect gpmc_cs_set_timings() caller to have initialized sync vs async
Note that this API is glitchy; likely the best fix would be to add
a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that
holds one key aspect of the GPMC timings (the gpmc_fclk divisor,
and sync vs. async == whether that divisor matters).

ARM: OMAP: MPUIO wake updates
GPIO and MPUIO wake updates:
- Hook MPUIOs into the irq wakeup framework too. This uses a platform
device to update irq enables during system sleep states, instead of
a sys_device, since the latter is no longer needed for such things.
- Also forward enable/disable irq wake requests to the relevant GPIO
controller, so the top level IRQ dispatcher can (eventually) handle
these wakeup events automatically if more than one GPIO pin needs to
be a wakeup event source.
- Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such
read-only data under the spinlock.
This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without
a 15xx I can't test such stuff.
Also this expects the top level IRQ dispatcher to properly handle requests
to enable/disable irq wake, which is currently known to be wrong: omap1
saves the flags but ignores them, omap2 doesn't even save it. (Wakeup
events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...)
So MPUIO irqs won't yet trigger system wakeup.

It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2.
Those should be able to switch easily to this version, and clean up
some of the omap1-specific code.
In addition to H4 support, one key improvement is supporting not just
the "old" ARM debug LED API (with timer and idle LEDs, plus four that
can be handy for kernel debugging), but it also supports the "new"
generic LED API (most useful for usermode stuff IMO). Either or both
APIs can be enabled.
