This patchset resolve some Loongson-related pci problems (however, some
of them affect not only Loongon platform). The first patch has been sent
before, and nearly all reviewers' questions had been answered at that
time [1]. The second patch move some LS7A quirks to quirks.c, where can
be shared by multi architectures. The third patch improve the mrrs quirk
for LS7A chipset, and the fourth patch add a new quirk for LS7A chipset.
