Add support of "FWU_MDATA" partition type in flashlayout to select the TF-A firmware update metadata partition type guid, associated to U-Boot "system" partition type guid, FWU_MDATA_GUID introduced by commit 2eaedc95164f ("FWU: Add FWU metadata structure and driver for accessing metadata") and used in gpt_get_mdata_partitions() for commit 554b38f7a532 ("FWU: Add FWU metadata access driver for GPT partitioned block devices")
See also recommendation in FWU-PSA-A_DEN0118_1.0ALP3.pdf 4.1.2 Metadata integration with GPT When embedded in a GPT, each metadata replica occupies a single partition with PartitionTypeGUID = metadata_uuid. UUID = 8a7a84a0-8387-40f6-ab41-a8b9a5a60d23
