pxa_pm_prepare() tried to validate the suspend method type.  As
noted in previous commits:
	eb9289eb
	9c372d06
	e8c9c502

the checking of the suspend type in the 'prepare' method is the
wrong place to do this; use the 'valid' method instead.  This
means that pxa_pm_prepare() can be entirely removed.

Move the pm_ops structure into the PXA25x and PXA27x support
files.  Remove the old pxa_pm_prepare() function, and rename
the both pxa_cpu_pm_prepare() functions as pxa_pm_prepare().
We'll fix that later.

Patch from Todd Poynor

Add symbols for PXA2xx PWRMODE register M field that selects low-power
mode, replace unadorned constants.  Honor power mode parameter of
pxa_cpu_suspend(mode), no longer force to 3 (sleep).  Full Deep Sleep
low-power mode support for PXA27x is pending generic PM interfaces to
select more than 2 suspend-to-RAM-style power modes, but this is
expected soon. This can be hardcoded in the meantime by replacing the
pxa_cpu_suspend() parameter value.  From David Burrage and Todd Poynor.
Try #2 removes one of the register copies and moves the code to save the
pxa_cpu_suspend parameter to immediately surround the call that requires
the parameter value be preserved.

Patch from Todd Poynor

PXA27x sleep fixes:
* set additional sleep/wakeup registers for Mainstone boards.
* move CKEN=0 to pxa25x-specific code; that value is harmful on pxa27x.
* save/restore additional registers, including some found necessary for
C5 processors and/or newer blob versions.
* enable future support of additional sleep modes for PXA27x (eg,
standby, deep sleep).
* split off cpu-specific sleep processing between pxa27x and pxa25x into
separate files (partly in preparation for additional sleep modes).
Includes fixes from David Burrage.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
