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.

Pull mailbox updates from Jassi Brar:
"Mainly we move from jiffy based timer to HRTIMER for finer control
over polling. Then a controller reduces its polling period from 10 to
1ms"
* 'mailbox-for-next' of git://git.linaro.org/landing-teams/working/fujitsu/integration:
mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 ms
mailbox: switch to hrtimer for tx_complete polling
mailbox: Drop owner assignment from platform_driver
Since the mailbox core users hrtimers now, it can handle much higher
resolutions. We can reduce the txpoll_period to 1 ms as the transmit
usually takes just few microseconds.
