can: rcar_canfd: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert the Renesas R-Car CAN-FD 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.
