Pali Rohár c06597ff11 pci: mpc85xx: Do not access PCI BARs registers of BDF address 00:00.0 
At BDF address 00:00.0 is fictional device which PCI configuration header
is for configuring mpc85xx PCI controller itself. PCI config space of this
device has ATMU inbound registers on position of PCI BARs. Trying to do PCI
auto configuration of this device cause rewriting ATMU inbound registers.
To avoid it, do not allow overwriting registers at BARs positions. And
because this device does not have any PCI memory, return zeros when trying
to read PCI BARs config space registers. It signals to auto configuration
tool to not allocate any PCI memory for this device.

17.3.1.3, 17.3.1.1.1, 17.3.2 and 17.3.2.11. Available at NXP website:
