hw/sd/omap_mmc: Use similar API for "wire up omap_clk" to other OMAP devices

The approach we've settled on for handling the omap_clk wiring for
OMAP devices converted to QDev is to have a function omap_foo_set_clk()
whose implementation just sets the field directly in the device's
state struct. (See the "TODO" comment near the top of omap.h.)
Make omap_mmc do the same.
