ENGR00227241 mx6sl: clk: sdhc can not work at lp idle mode
issue:
Once entering low power idle mode, pll2_400 will be bypass which will change
the clk rate of sdhc root clk. so far, there's no mechanism to inform sdhc
for changing of root clk in current driver structure.
fix:
Revert "ENGR00226096 mx6sl: remove high set point for usdhc"
This reverts commit 97aee96a34ca63da0d1d602a19b3a444352e5803.
