mmc: sdhci-of-dwcmshc: add reset call back for rockchip Socs

Browse source

The reset function build in the SDHCI will not reset the logic
circuit related to the tuning function, which may cause data
reading errors. Resetting the complete SDHCI controller through
the reset controller fixes the issue.
