mmc: sdhci-of-dwcmshc: move rxclk non-invert code to .set_clock()

Browse Source 
This setting will be lost during deep suspend in case of powering
off the controller. So we need to always recovery it when calling
resume hook. But .set_clock() will be awlays called whenever the
driver's probed or resumed. So we move it there.
