Modify the UFSHCD core to allow 'struct ufshcd_sg_entry' to be variable-length. The default is the standard length, but variants can override ufs_hba::sg_entry_size with a larger value if there are vendor-specific fields following the standard ones. This is needed to support inline encryption with ufs-exynos (FMP).
