Alex Zhao b59b1c0040 mmc: add a file to debugfs for changing host max clock at runtime 
Usage is as follows:

rk3566_rgo:/ # cat /sys/kernel/debug/mmc1/max_clock
150000000

rk3566_rgo:/ # echo 200000000 > /sys/kernel/debug/mmc1/max_clock
rk3566_rgo:/ # cat /sys/kernel/debug/mmc1/max_clock
200000000
rk3566_rgo:/ # echo 200000000 >  /sys/kernel/debug/mmc1/clock

rk3566_rgo:/ # dmesg -c
[  285.884348] mmc_host mmc1: Bus speed (slot 0) = 198000000Hz (slot req 200000000Hz, actual 198000000HZ div = 0)
