Jassi Brar 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.
