[PATCH 1/2] regmap: regmap-irq: Move handle_post_irq to before pm_runtime_put

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

Typically handle_post_irq is going to be used to manage some
additional chip specific hardware operations required on each IRQ,
these are very likely to want the chip to be resumed. For example the
current in tree user max77620 uses this to toggle a global mask bit,
which would obviously want the device resumed. It is worth noting this
device does not specify the runtime_pm flag in regmap_irq_chip, so
there is no actual issue.

Move the callback to before the pm_runtime_put, so it will be called
whilst the device is still resumed.
