Subject: [PATCH 07/19] powerpc/powermac: Make some functions static

These functions can all be static, make it so. Fix warnings treated as
errors with W=1:

  arch/powerpc/platforms/powermac/pci.c:1022:6: error: no previous prototype for ‘pmac_pci_fixup_ohci’ [-Werror=missing-prototypes]
  arch/powerpc/platforms/powermac/pci.c:1057:6: error: no previous prototype for ‘pmac_pci_fixup_cardbus’ [-Werror=missing-prototypes]
  arch/powerpc/platforms/powermac/pci.c:1094:6: error: no previous prototype for ‘pmac_pci_fixup_pciata’ [-Werror=missing-prototypes]

Also add gcc attribute unused to fix a warning treated as error with W=1:

  arch/powerpc/platforms/powermac/pci.c:784:19: error: variable ‘has_address’ set but not used [-Werror=unused-but-set-variable]
  arch/powerpc/platforms/powermac/pci.c:907:22: error: variable ‘ht’ set but not used [-Werror=unused-but-set-variable]
