ENGR00117737-2 MX28 SD/MMC/SDIO
Enable the ssp mmc port0~1, the set_rate, set_parent
to refio.0 clock, and the HighSpeed mode, SD up to
4bits and 50MHz, MMC up to 8bits and 52MHz.
Resolved the urgly IO bench and some cards
unrecognization issues.
The root cause is the clk unit of clock should
be Hz, but not the KHz
