m68k: coldfire: use clkdev_lookup on most coldfire

Browse source 
Coldfire is now the only target that implements the clk_get()/clk_put()
helpers itself rather than using the common implementation.

Most coldfire variants only have two distinct clocks and use the clk
code purely for lookup. Change those over to use clkdev_lookup instead
but leave the custom clk interface for those two clocks.

Also leave the four SoCs that have gated clocks.
