[PATCH RFC 17/31] mmc: sdhci: move setting host->clock into sdhci_do_set_ios()

[Russell King]

We don't need implementations to do this, since the only time it's
necessary is when we change the clock, and the only place that happens
is in sdhci_do_set_ios().  So, move it there, and remove it from the
iMX platform backend.
