Subject: [PATCH 3/5] firmware: arm_ffa: Align sync_send_receive{,2}
 function prototypes

Currently ffa_sync_send_receive2() takes UUID as a separate parameter
instead of using the one available in ffa_device structure.

Change the prototype of ffa_sync_send_receive2() to align with the
ffa_sync_send_receive() and use ffa_device->uuid.
