A recent discussion about legacy clk interface users revealed
that there are only two platforms remaining that provide their own
clk_get()/clk_put() implementations, MIPS ar7 and and m68k coldfire.

I managed to rework both of these to just use the normal clkdev code,
and fold CONFIG_CLKDEV_LOOKUP into CONFIG_HAVE_CLK as it is now shared
among all users.

As I noticed that the ar7 clock implementation and the ralink version
are rather trivial, I ended up converting those to use the common-clk
interfaces as well, though this is unrelated to the other changes.

   mips: ar7: convert to clkdev_lookup

   mips: ralink: convert to CONFIG_COMMON_CLK
   m68k: coldfire: use clkdev_lookup on most coldfire
   m68k: coldfire: remove private clk_get/clk_put
   clkdev: remove CONFIG_CLKDEV_LOOKUP
   clkdev: remove unused clkdev_alloc() interfaces

Looks really good, thanks for doing this.

I have test compiled and run some of the ColdFire targets with these changes.
Everything checked out good. So for the m68k/Coldfire parts (with the one
munged writew() change fixed):
