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.

I think you'll find you just broke the build.

What happens when you compile these as modules?
I build as modules with no warning or error, did you find anything wrong?
Yes, you don't export the functions.

EXPORT_SYMBOL()
No need export symbol, all rts52xx.c and rtsx_pcr.c will build into a single rtsx_pci.ko file.
and we do not want these functions to be called in other place.
Because they are not a good interface, and may be changed in the future.
