mmc: core: modify scaling up/down sequence
The scaling down sequence requires the clock to be set
after selecting the corresponding bus-speed mode in the
controller.
The scaling up to HS400 requires the timing and clock to
be set to legacy.
Without the above configuration, bus-width switch fails,
further leading to CRC errors.
