Hi guys,
I found a similar issue on rk3399 platform, which has a genpd node for
SD card host. Power off-on pd will reset the registers to a default
value (
("mmc: dw_mmc: add runtime PM
callback"). MMC_PM_KEEP_POWEP is disabled for SD card and eMMC slots, so
that they have no chance to invoke dw_mci_setup_bus for update clock
behaviour. Let's consummate it.

Without this series of patches, we can't gate aclk_emmcgrf even though
driver enter suspend/remove. It meaningful to save power consumption.
It looks nice to me, and also I have tested on rk3399 board, so
