thermal/drivers/clock_cooling: Remove clock_cooling code

clock_cooling has no in-kernel users. It has never found any use in
drivers as far as I can tell.

Remove the code.

This entry implements the generic clock cooling mechanism through
frequency clipping. Typically used to cool off co-processors. The
device that is configured to use this cooling mechanism will be
controlled to reduce clock frequency whenever temperature is high.
