ANDROID: scsi: ufs: fix collision between CRYPTO and RPM_AUTOSUSPEND bits

On android-5.4, UFSHCD_CAP_CRYPTO was assigned bit (1 << 6), then a
patch was backported from upstream which added
UFSHCD_CAP_RPM_AUTOSUSPEND, also as (1 << 6).

This bug is not present in android-4.19 or android-mainline, where
UFSHCD_CAP_CRYPTO is bit (1 << 7) instead.

Fix android-5.4 to do that too.
