firmware: arm_ffa: Set the core device as FF-A device parent
Pass a parent device into ffa_device_register() and use the synthetic
arm-ffa platform device as the parent for each registered FF-A device.
This keeps the enumerated FF-A partition devices anchored below the FF-A
core device in the driver model, matching the platform-driver conversion
of the core transport.
