mmc: dw_mmc: update actual clock for mmc debugfs
Respect the actual clock for mmc debugfs to help better debug
the hardware.
mmc_host mmc0: Bus speed (slot 0) = 135475200Hz (slot req 150000000Hz,
actual 135475200HZ div = 0)
cat /sys/kernel/debug/mmc0/ios
clock: 150000000 Hz
actual clock: 135475200 Hz
vdd: 21 (3.3 ~ 3.4 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 3 (8 bits)
timing spec: 9 (mmc HS200)
signal voltage: 0 (1.80 V)
driver type: 0 (driver type B)
