Russell King 58c19a140d PCI: mvebu: Return zero for reserved or unimplemented config space 
PCI requires reads to reserved or unimplemented configuration space to
return zero and complete normally (see PCI r3.0, sec 6.1).  However, the
root port software implementation was returning 0xfffffff and
PCIBIOS_BAD_REGISTER_NUMBER.

Return zero when reading reserved or unimplemented config space.
