Samuel Holland 6d8664d459 bus: sunxi-rsb: Support atomic transfers ...

[ Upstream commit 077686da0e2162c4ea5ae0df205849c2a7a84479 ]

When communicating with a PMIC during system poweroff (pm_power_off()),
IRQs are disabled and we are in a RCU read-side critical section, so we
cannot use wait_for_completion_io_timeout(). Instead, poll the status
register for transfer completion.
