The newly added sdhci_msm_restore_sdr_dll_config() function is only
called if CONFIG_PM is enabled:

drivers/mmc/host/sdhci-msm.c:1050:12: error: 'sdhci_msm_restore_sdr_dll_config' defined but not used [-Werror=unused-function]

Better remove the incorrect #ifdef altogether and just use __maybe_unused,
which is harder to get wrong.

Fixes: ec3349733550 ("mmc: sdhci-msm: Re-initialize DLL if MCLK is gated dynamically")
