drm/mediatek: mtk_hdmi: Remove ifdef for CONFIG_PM_SLEEP

Since the SIMPLE_DEV_PM_OPS macro and the pm pointer are anyway
defined when CONFIG_PM_SLEEP is not set, remove the ifdef for it
and indicate that the mtk_hdmi_{remove,suspend} functions may be
unused (as they are, in case PM support is not built-in).

While at it, to improve readability, also compress the
SIMPLE_DEV_PM_OPS declaration as it even fits in less
than 80 columns.
