drivers:optee:rpmb: initialize drivers of mmc devices in UCLASS_BLK for rpmb access

CONFIG_MMC only initializes drivers for devices in UCLASS_MMC, we need
to initialize drivers for devices of type IF_TYPE_MMC in UCLASS_BLK as
well because they are the child devices of devices in UCLASS_MMC.  This
is required for feature RPMB since it will access eMMC in optee-os.
