clk: clean up legacy clock interfaces

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.

Stephen offered to merge these through the clk tree. I was waiting
for an Ack/Nack from the MIPS/ar7/ralink maintainers but got no further
reply, so sending this as a pull request now.

Please pull or apply, assuming there are no further concerns.

Changes since v1:
 - fix two typos on coldfire
 - remove duplicate #include
 - rebased to v5.13-rc1 to avoid backmerge

Arnd Bergmann (7):
  mips: ar7: convert to clkdev_lookup
  mips: ar7: convert to CONFIG_COMMON_CLK
  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
