Fix rts5227&5249 failed send buffer cmd after suspend,
PM_CTRL3 should reset before send any buffer cmd after suspend.
Otherwise, buffer cmd will failed, this will lead resume fail.

These are Card Reader drivers right?

Do you know why these are in MFD?
Hi Lee,

Our chips support SD/MMC card and MS card,
SD/MMC card driver is put into mmc/ subsystem,
MS card driver is put into memstick/ subsystem.
We put the common functions into mfd/ subsystem.
