Levi Yun 6fe437cfe2 firmware: arm_ffa: Fix the race around setting ffa_dev->properties 
Currently, ffa_dev->properties is set after the ffa_device_register()
call return in ffa_setup_partitions(). This could potentially result in
a race where the partition's properties is accessed while probing
struct ffa_device before it is set.

Update the ffa_device_register() to receive ffa_partition_info so all
the data from the partition information received from the firmware can
be updated into the struct ffa_device before the calling device_register()
in ffa_device_register().
