simplefb gets unregister when a proper framebuffer driver comes in and

Move the clock/regulator cleanup into the framebuffer destroy callback,
which gets called as part of the framebuffer unregister process.
Is this called before or after the new proper framebuffer driver kicks in?
If before, it may cause glitches.
It is called by the new proper framebuffer driver's probe method,
so it can make sure that it has already claimed / enabled the
clocks/regulators before it calls remove_conlicting_framebuffers,
avoiding the glitch.
