mmc: dw_mmc: fixed a wrong UHS_REG 16 bit clear
In the legacy code, driver clear not only UHS_REG 16 bit also 0-15bit.
If we use UHS-1 mode spec card like SDR50, SDR104. UHS_REG 0-15 should
be set by 1 according to slot id. In this case, legacy code can cause
problems.
In particular, UHS_REG consists of DDR_REG[31:16] and VOLT_REG[15:0].
Before adjusting this patch, bit[15:0] is always cleared.
