Subject: x86/PCI: never allocate PCI MMIO resources below BIOS_END

x86/PCI: never allocate PCI MMIO resources below BIOS_END

When we move a PCI device or assign resources to a device not configured
by the BIOS, we want to avoid the BIOS region below 1MB.  Note that if the
BIOS places devices below 1MB, we leave them there.
