[ARM] 2787/2: PXA27x low power modes support
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.
