The driver has just gained a slightly incorrect pm-sleep implementation that
causes
warnings when CONFIG_PM is set but CONFIG_PM_SLEEP is not:
drivers/mmc/host/sdhci-esdhc-imx.c:1302:12: error: 'sdhci_esdhc_resume' defined
but not used [-Werror=unused-function]
static int sdhci_esdhc_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~
drivers/mmc/host/sdhci-esdhc-imx.c:1297:12: error: 'sdhci_esdhc_suspend'
defined but not used [-Werror=unused-function]
static int sdhci_esdhc_suspend(struct device *dev)
This replaces the incorrect #ifdef with a __maybe_unused annotation that does
the right thing in all configurations and is more readable.

callback")
