David Brownell 994c84ea52 ARM: OMAP: h4 must have blinky leds!!
This adds generic support for the "debug board" LEDs used by most of
TI's OMAP reference boards, and board-specific support for the H4.

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.

David Brownell 11a78b7944 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.

More GPIO/IRQ cleanup:

  - compile-time removal of much useless code

      * 15xx/730/24xx gpio support on 1610
      * 15xx/730/16xx gpio support on 24xx
      * etc

  - remove all BUG() calls, which are always bad news ... replaced some
    with normal fault reports for that call, others with WARN_ON(1).

  - small mpuio bugfix:  add missing set_type() method

Oh, and fix a minor merge issue: inode->u.generic_ip is now gone.
