mmc: renesas_sdhi: Switch to SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() and pm_ptr()

SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() require __maybe_unused
or #ifdefs protection against unused function warnings. The usage of
pm_ptr() and SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() allows the compiler to
see the functions, thus suppressing the warning. Drop the #ifdefs.
