[PATCH] irqchip: st: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[Triet Hoang]

Convert the deprecated SIMPLE_DEV_PM_OPS
to DEFINE_SIMPLE_DEV_PM_OPS
and pm_sleep_ptr().

This lets us drop the __maybe_unused annotations
from its suspend and resume callbacks,
also reduces kernel size in case CONFIG_PM or
CONFIG_PM_SLEEP is disabled.

Thanks for the patch! The patch itself (the code change part) looks
good to me. You can improve a little bit on the commit message format:
 * Please realign the text to a 72 characters line width.
 * Please avoid using the first person in the second paragraph. For
   example, something like "This allows dropping the..." is better.

Thanks for your review! Should I send the v2 to improve this?
