mmc: mediatek: mark PM functions as __maybe_unused
The #ifdef check for the suspend/resume functions is wrong:
drivers/mmc/host/mtk-sd.c:2765:12: error: unused function 'msdc_suspend' [-Werror,-Wunused-function]
static int msdc_suspend(struct device *dev)
drivers/mmc/host/mtk-sd.c:2779:12: error: unused function 'msdc_resume' [-Werror,-Wunused-function]
static int msdc_resume(struct device *dev)
Remove the #ifdef and mark all four as __maybe_unused to aovid the
problem.
Fixes: c0a2074ac575 ("mmc: mediatek: Fix system suspend/resume support for CQHCI")
