mailbox: arm_mhu: Match only if compatible is "arm,mhu"

Browse Source 
Since we will be soon adding a separate driver based on this ARM MHU
driver to support doorbell mode, let us add explicit check to match
the default compatible for this driver. This is needed as the probe
and match reuses the AMBA device ids currently and don't have any
explicit compatible check.
