When system enters S0ix, system fails to power gate SD card
controller.
This patch implements PM methods to put the SD card controller
in D3 during S0ix entry.
TEST=Suspend and resume using 'echo freeze > /sys/power/state'.
The System should not be blocked by sd card controller.

Two W/A had been added here for EMMC to make it working properly.
1. Enable power gating after D3 entry, disable power gating before D0
entry.
2. Add 50 ms delay to ensure Rcomp calibration done before EMMC out of
D3.
