Frank Li f6c574df24 mmc: sdhci-esdhc-imx: fix kernel panic when remove module 
commit a56f44138a2c57047f1ea94ea121af31c595132b upstream.

In sdhci_esdhc_imx_remove() the SDHCI_INT_STATUS in read. Under some
circumstances, this may be done while the device is runtime suspended,
triggering the below splat.

Fix the problem by adding a pm_runtime_get_sync(), before reading the
register, which will turn on clocks etc making the device accessible again.
