In version 2 of the metadata structure, the size of the structure
cannot be determined statically at build time. The structure is now
broken into the top level structure which contains a field indicating
the total size of the structure.
Add a size parameter to the metadata access API functions to indicate
the number of bytes to be accessed. This is then used to either read
the entire structure, or only the top level structure.

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.

Moving towards using common code for meta-data management,
implement the read/write mdata hooks.

Use cached values and avoid parsing and scanning through partitions
everytime for meta-data partitions because they can't change after bootup.

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.
