Chen Lifu 59dc2d94bc powerpc/powermac: Fix symbol not declared warnings
1. ppc_override_l2cr and ppc_override_l2cr_value are only used in
   l2cr_init() function, remove them and used *l2cr directly.
2. has_l2cache is not used outside of the file, so mark it static and
   do not initialise statics to 0.

Fixes the following warnings:

  arch/powerpc/platforms/powermac/setup.c:73:5: warning: symbol
  'ppc_override_l2cr' was not declared. Should it be static?
  arch/powerpc/platforms/powermac/setup.c:74:5: warning: symbol
  'ppc_override_l2cr_value' was not declared. Should it be static?
  arch/powerpc/platforms/powermac/setup.c:75:5: warning: symbol
  'has_l2cache' was not declared. Should it be static?
