ANDROID: Add padding for crypto related structs in UFS and MMC

Browse source 
Add padding to ufshcd_host and ufshcd_hba_variant_ops UFS, and mmc_host
in MMC to allow expansions in future if necessary, while keeping the
ABI stable. These fields are only for the purposes of keeping the ABI
stable, and in particular are *NOT* for vendor use.
