ux500-pm: "ApDeepSleep" low power state support
This patch adds the "ApDeepSleep" low power state for the
U8500 platform. The ApDeepSleep is the lowest power state,
both the core/ape turned off. This low power mode can now be
entered/exited through the standard linux PM framework
echo mem > /sys/power/state will put the core into the deep sleep
state. The system can be woken up from USB insertion, console,
RTC events back to the execute mode.
This patch
- cleans existing non-working deepsleep code from PRCMU f/w file
- cleans redundant code for cpu hotplug
- re-orgs the platform pm.c file for supporting
uart2/gic/icn/prcc peripheral contexts
- fixes FIDO_IR_ER: 258539, make UART2 console as a wakeup event
- incorporates review comments from gerrit
The "ApSleep" power state can now be entered through the
echo standby > /sys/power/state command.
FIDO_IR_ER: 258539, add deep sleep support
FIDO_IR_ER: 258539, make UART2 console as a wakeup event
