clk: rs9: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert the Renesas 9-series PCIe clock generator driver from
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.
