246ec2a12c fwu: meta-data: switch to management by common code
The common code can now read, verify and fix meta-data copies
while exposing one consistent structure to users.
 Only the .read_mdata() and .write_mdata() callbacks of fwu_mdata_ops
are needed. Get rid of .get_mdata() .update_mdata() .get_mdata_part_num()
.read_mdata_partition() and .write_mdata_partition() and also the
corresponding wrapper functions.

b042c70554 fwu: gpt: use cached meta-data partition numbers
Use cached values and avoid parsing and scanning through partitions
everytime for meta-data partitions because they can't change after bootup.

554b38f7a5 FWU: Add FWU metadata access driver for GPT partitioned block devices
In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, on a separate
partition. Add a driver for reading from and writing to the metadata
when the updatable images and the metadata are stored on a block
device which is formatted with GPT based partition scheme.
