[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.
