firmware: arm_ffa: Update the FF-A command list with v1.1 additions

Browse Source 
Arm Firmware Framework for A-profile(FFA) v1.1 introduces notifications
and indirect messaging based upon notifications support and extends some
of the memory interfaces.

Let us add all the newly supported FF-A function IDs in the spec.
Also update to the error values and associated handling.
