mmc: Add support for HI3660 SoC reusing hi6220_dw_mmc driver
This commit adds MMC driver support for HI3660 SoC reusing hi6220_dw_mmc
driver. Since HI3660 operates at different clock rate and uses fifo
mode now, let's introduce the platform data and utilize it for different
SoCs supported by this driver.
