media: renesas: ceu: Convert to RUNTIME_PM_OPS() 



Convert the Renesas Capture Engine Unit driver from SET_RUNTIME_PM_OPS()
to RUNTIME_PM_OPS() and pm_ptr().  This lets us drop the __maybe_unused
annotations from its runtime suspend and resume callbacks, and reduces
kernel size in case CONFIG_PM is disabled.
