musb_hdrc: Update host side EP0 handling for correctness

Update host side EP0 handling for correctness:  handle zero-length data
stages and continuations of ep0out transfers explicitly, clean up the state
machine a bit.  This means that the full set of host-side ep0 tests pass.
Usbtest cases #9 and #10 were ok before; now case #14 works too.

There is however a curious protocol problem in some full speed tests, at
least on DaVinci:  sometimes the controller won't ack an IN DATA packet,
causing a retry.  If the peripheral doesn't resend that data correctly,
that causes a test failure.  (And my test rig doesn't resend correctly...)

This is based on a patch from "ZHENG LEI <realthunder@pmail.ntu.edu.sg>"
against 2.6.10 code, resolving some of the ep0out problems.

musb_hdrc: Minor cleanups involving name changes

Minor cleanups involving name changes, primarily on the peripheral side:

 - musb->bMayWakeup becomes may_wakeup (camelcase bad)
 - musb->bIsSelfPowered becomes is_self_powered (camelcase bad)
 - pThis (as parameter or variable) becomes musb (camelcase bad)
 - tusb_set_power becomes tusb_draw_power (more meaningful name)
 - tusb_set_vbus becomes tusb_source_power (more meaningful name)

Also, add a flag to track if a B-Peripheral device draws any VBUS power
(currently only tusb6010 can set that).

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.

ARM: OMAP: USB peripheral support on H4

H4 has two peripheral ports, one for "download" and one for OTG.
The one to use is selected through Kconfig.

NOTE:  not yet working; I suspect there's a clock still turned off
or something like that, since neither port responds.
