This series was to get all the additional save/restores needed for the
rtc+ddr mode. Caller patch is in the main patch that implements that
mode that i will be posting once the ground is set.

Based on enable_off_mode being set this function was called only for
rtc+ddr mode.

I will look into that. Thanks for suggestion.

Oops yes that should be pinctrl.
