This patch (as1482) adds a macro for testing whether or not a
pm_message value represents an autosuspend or autoresume (i.e., a
runtime PM) event.  Encapsulating this notion seems preferable to
open-coding the test all over the place.

Some of the entry points to pm runtime are not safe to
call in atomic context unless pm_runtime_irq_safe() has
been called.  Inspecting the code, it is not immediately
obvious that the functions sleep at all, as they run
inside a spin_lock_irqsave, but under some conditions
they can drop the lock and turn on irqs.

If a driver incorrectly calls the pm_runtime apis, it can
cause sleeping and irq processing when it expects to stay
in atomic context.

Add might_sleep_if to the majority of the __pm_runtime_* entry points
to enforce correct usage.

Add pm_runtime_put_sync_autosuspend to the list of
functions that can be called in atomic context.

Function genpd_queue_power_off_work() is not defined for
CONFIG_PM_RUNTIME, so pm_genpd_poweroff_unused() causes a build
error to happen in that case.  Fix the problem by making

pmbus_clear_faults() attempts to clear faults on non-existing real pages.
As a result, the command error bit in the status register is set, and faults
are not really cleared.

All byte writes to non-zero pages are requests to clear the status register
on that page. Since non-zero pages are virtual and do not exist on the chip,
there is nothing to do, and such requests have to be ignored. This fixes
above problem.

This cleans up error handling for the beacon in case of dma mapping
failure.  We need to free the skb when dma mapping fails instead of
nulling and leaking the pointer, and we should bail out to avoid
giving the hardware the bad descriptor.

Finally, we need to perform the null check after trying to update
the beacon, or else beacons will never be sent after a single
mapping failure.
