x86/PCI: Ignore _CRS on Supermicro X8DTH-i/6/iF/6F
commit 89e9f7bcd8744ea25fcf0ac671b8d72c10d7d790 upstream.
Martin reported that the Supermicro X8DTH-i/6/iF/6F advertises incorrect
host bridge windows via _CRS:
pci_root PNP0A08:00: host bridge window [io 0xf000-0xffff]
pci_root PNP0A08:01: host bridge window [io 0xf000-0xffff]
Both bridges advertise the 0xf000-0xffff window, which cannot be correct.
Work around this by ignoring _CRS on this system. The downside is that we
may not assign resources correctly to hot-added PCI devices (if they are
possible on this system).
