Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Let's move cputype.h away from mach-mmp/ so that the drivers outside that
directory are able to tell the precise silicon revision. The MMP3 USB OTG
PHY driver needs this.

The mach/*.h headers are now inaccessible to any external code,
so we can move them all into the mach-mmp directory itself
and remove the subdirectories.
A few headers are not used at all, so we remove them here.

The pm-mmp2 and pm-pxa910 power management related irq_set_wake
callbacks fiddle pointlessly with the irq actions for no reason except
for lack of understanding how the wakeup mechanism works.
On supsend the core disables all interrupts lazily, i.e. it does not
mask them at the irq controller level. So any interrupt which is
firing during suspend will mark the corresponding interrupt line as
pending. Just before the core powers down it checks whether there are
interrupts pending from interrupt lines which are marked as wakeup
sources and if so it aborts the suspend and resends the interrupts.
If there was no interrupt at this point, the cpu goes into suspend
with these interrupts unmasked.
The IRQF_NO_SUSPEND flag for interrupt actions is a totally different
mechanism. That allows the device driver to prevent the core from
disabling the interrupt despite the fact that it is not marked as a
wakeup source. This has nothing to do with the case at hand. It was
introduced for special cases where lazy disable is not possible.
Remove the nonsense along with the braindamaged boundary check. The
core code does NOT call these functions out of boundary.
Add a FIXME comment to an unhandled error path which merily printks
some useless blurb instead of returning a proper error code.

MMP2 can enter system sleep level during suspend.
It can be waken up by PMIC interrupt, RTC/ALARM.
