SDHCI: Add change_clock callback for glue drivers

Add a change_clock callback to allow drivers to update
device specific clock selections and control registers
when there is a change in clock.

Move the main part of sdhci_set_clock() to a new routine
which can be called by the glue drivers to do the sdhci
standard clock management.

Update the sdhci-s3c driver to use this to select the
appropriate clock source when clocks change.
