robert-hh 11cf742524 rp2/modmachine: Allow changing CPU clock frequency. 
Using the standard machine.freq().

The safe ranges tested were 10 and 12-270MHz, at which USB REPL still
worked.  Requested settings can be checked with the script:
pico-sdk/src/rp2_common/hardware_clocks/scripts/vcocalc.py.  At frequencies
like 300MHz the script still signaled OK, but USB did not work any more.
