Shawn Lin 237c6759e4 mmc: sdhci-of-dwcmshc: Disable clock before DLL configuration 
[ Upstream commit 6546a49bbe ]

According to the ASIC design recommendations, the clock must be
disabled before operating the DLL to prevent glitches that could
affect the internal digital logic. In extreme cases, failing to
do so may cause the controller to malfunction completely.

Adds a step to disable the clock before DLL configuration and
re-enables it at the end.

[ dropped HS200/HS400 block and BIT(4) line, converted the single `return` in `if (clock <= 400000)` to `goto enable_clk` ]
