Sean Cross b805db0444 efm32: cmu: support switching HFCLK to USHFRCODIV2 ...

Allow for the high frequency clock that controlls things such as the
main CPU to be switched over to USHFRCODIV2.  This is a 24 MHz PLL
that is trimmed using clock recovery from the USB signal, and is
accurate to within 1% of 24 MHz.
