Subject: [PATCH net-next 2/3] sh_eth: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert the Renesas SuperH Ethernet driver from an open-coded dev_pm_ops
structure to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr().  This lets
us drop the checks for CONFIG_PM and CONFIG_PM_SLEEP without impacting
code size, while increasing build coverage.
