[PATCH 18/26] drm: rockchip: Remove #ifdef guards for PM related functions

Use the pm_sleep_ptr() macros to handle the .suspend_late /
.resume_early callbacks.
This macro allows the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
