serial: sh-sci: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert the Renesas SuperH SCI(F) serial port 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.
