PCI: loongson: Use generic 8/16/32-bit config ops on LS2K/LS7A

Browse source

LS2K/LS7A support 8/16/32-bits PCI config access operations via CFG1, so
we can disable CFG0 for them and safely use pci_generic_config_read()/
pci_generic_config_write() instead of pci_generic_config_read32()/pci_
generic_config_write32().
