2015-03-13ARM: at91/pm: remove unused void (*at91_pm_standby)(void)Wenyou Yang1-4/+1

2015-03-13ARM: at91/pm: standby mode uses same sram function as suspend to memory modeWenyou Yang3-47/+73
To simply the PM code, the suspend to standby mode uses same sram function as the suspend to memory mode, running in the internal SRAM, instead of the respective code for each mode. For the suspend to standby mode, the master clock doesn't switch to the slow clock, and PLLA and the main oscillator doesn't turn off as well.

There is not much we can do if a PLL lock never ends, we are running in SRAM and we will not be able to connect back the sdram or ddram in order to be able to fire up a message or just panic.
