thermal/drivers/rcar_gen3: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert the Renesas R-Car Gen3 thermal driver from SIMPLE_DEV_PM_OPS()
to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr().  This lets us drop the
__maybe_unused annotation from its resume callback, and reduces kernel
size in case CONFIG_PM or CONFIG_PM_SLEEP is disabled.
