stm32: rcc: Rationalize MCO definitions

Browse Source 
Some parts used HSICLK, some used HSI.  Most used NOCLK, f3 used
DISABLED.  Try and move all to the shorter, simpler forms, instead of
having mixed defines for different targets for the same thing.  Just
because the bits themselves are different doesn't mean we should make it
more difficult for users to port code.
