powerpc/cpm1: Mark micropatch code/data static and __init

This saves runtime memory and fixes lots of sparse warnings like this:

    CHECK   arch/powerpc/sysdev/micropatch.c
  arch/powerpc/sysdev/micropatch.c:27:6: warning: symbol 'patch_2000'
  was not declared. Should it be static?
  arch/powerpc/sysdev/micropatch.c:146:6: warning: symbol 'patch_2f00'
  was not declared. Should it be static?
  ...
