Karl Palsson 093edfb881 doc: efm32: cmu: move to peripheral_apis 
Was completely undocumented before. Just needed different tagging so it
could be picked up.

No attempt at this stage of sharing more code between the cmu modules.

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.
