As reported by lkp:
arch/powerpc/platforms/83xx/km83xx.c:183:19: error: 'mpc83xx_setup_pci' undeclared here (not in a function)
183 | .discover_phbs = mpc83xx_setup_pci,
| ^~~~~~~~~~~~~~~~~
| mpc83xx_setup_arch
There is a stub defined for the CONFIG_PCI=n case, but now that
mpc83xx_setup_pci() is being assigned to discover_phbs the correct
empty value is NULL.
Fixes: 83f84041ff ("powerpc/83xx: Move PHB discovery")
