Read the UFS device, unit and geometry descriptors to report each RPMB
region's size and reliable-write count, and build a 16-byte CID by
BLAKE2b-hashing the same device-id string the Linux kernel derives
(ufshcd_create_device_id() plus a "-R<region>" suffix), so OP-TEE derives
an RPMB key that matches Linux. Exposed via ufs_rpmb_get_region_info().
