I'm trying to avoid having to implement a new clock provider. The
whole point of the generic clk code is to consolidate code. It seems
silly to create a new clk provider which is 95% identical to Mike's
gated provider, if i can avoid it.

If i stuff it into clk_disable(), it means i cannot use the basic gate
clock Mike provides in the generic clock framework. Which is a shame,
since it does exactly what i want in terms of gating the clock.

If i can use unprepare(), which basic gate does not use, i can use
Mikes code, and just extend it. It is there, it is unused, so why not
use it?
