Remove usbhost_sar_fclk from the OMAP3 clock framework. The bit that
the clock was tweaking doesn't actually enable or disable a clock; it
controls whether the hardware will save and restore USBHOST state
when the powerdomain changes state. (That happens to coincidentally
enable a clock for the duration of the operation, hence the earlier
confusion.)
In place of the clock, mark the USBHOST powerdomain as supporting
hardware save-and-restore functionality.
