[PATCH 4/6] mci: sdhci: rockchip: Update pre-change delay for rockchip platform

[Sascha Hauer]

This is an adoption from Linux commit b75a52b0dda35 ("mmc: sdhci-of-dwcmshc:
Update DLL and pre-change delay for rockchip platform"). We already have
most of it, this only adds the pre-change delay part.
