Minor comments, otherwise this looks pretty good. Let's get it tested thoroughly before merging, however.

I have a small concern about this logic tree. If we go from an overclock state to a normal state, the Vreg will be set down before the frequency change, potentially leading to instability.
We should test that hypothesis thoroughly to see if it is a problem before actually changing code though.

PR to add the overclock logic detailed here:
#34 (comment)
This will also warn the user in
setclockif they request a frequency that's considered overclocking (currently >200 MHz). I tested with both rp2040 and rp2350 prawnblasters.
