dmaengine: rcar-dmac: Convert to NOIRQ_SYSTEM_SLEEP/RUNTIME_PM_OPS()

Convert the Renesas R-Car DMA Controller driver from
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() to
NOIRQ_SYSTEM_SLEEP_PM_OPS(), RUNTIME_PM_OPS(), and pm_ptr().  This lets
us drop the check for CONFIG_PM, and reduces kernel size in case
CONFIG_PM is disabled, while increasing build coverage.
