mmc: sdhci-msm: enable partial initialization in resume

Browse source 
Enable partial init on eMMC devices for using card Sleep/Awake
sequence (CMD5).

Card will be sent to Sleep state during runtime/system suspend
and will be woken up during runtime/system resume.
By using this sequence the card doesn't need full initialization
which gives time reduction in system/runtime resume path.
