[PATCH] drm: renesas: rz-du: mipi_dsi: Convert to RUNTIME_PM_OPS()

[Geert Uytterhoeven]

Convert the Renesas RZ/G2L MIPI DSI Encoder 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.
