firmware: arm_ffa: Replace UUID buffer to standard UUID format 



Currently ffa_partition_info structure holds the UUID in the format
compatible with the firmware interface. However, most of the functions
in the FF-A core driver deals directly with uuid_t type.

Replace UUID buffer to standard UUID format in the ffa_partition_info
structure.
