m68k: coldfire: use clkdev_lookup on most coldfire
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. Acked-by: Greg Ungerer <gerg@linux-m68k.org> Tested-by: Greg Ungerer <gerg@linux-m68k.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
