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.
