[PATCH 1/5] mfd: arizona: Disable PM runtime at start of driver removal

[Charles Keepax <ckeepax@opensource.wolfsonmicro.com>]

We don't want to trigger any PM runtime operations whilst we are tearing
down the driver, as things the suspend and resume callbacks rely on
might already have been destroyed. So disable PM runtime for the device
as the first step arizona_dev_exit.
