[PATCH] drivers/clk: 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, and reduces kernel size in case CONFIG_PM or
CONFIG_PM_SLEEP is disabled.
