We want to the higher speed for wifi module working.
Bootup kernel log: ... mmc_host mmc0: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz, actual 37125000HZ div = 0)
or run 'cat /sys/kernel/debug/clk/clk_summary |grep phase -C 1' to check Otherwise, the mmc0 will run 400khz defalult value to work.
