mmc: sdhci-msm: Register call back function for hibernation 



Register the restore call back function sdhci-msm driver
to support hibernation.

Set the flag to reset the ICE in SDHC restore path during
hibernation resume.This ensures ICE gets reset when
SDHC resumes in S2D.ICE needs to be reset only when
SDHC gets h/w reset(this is to keep SHDC and ICE in sync).
