media: renesas: fdp1: Convert to RUNTIME_PM_OPS()

Convert the Renesas Fine Display Processor 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.
