Freescale platform has class code = 0x0b2000, when it boots. This makes
kernel PCI bus code to setup these devices resulting into the following
notice information when trying to enable them:
pci 0000:00:00.0: ignoring class 0x0b2000 (doesn't match header type 01)
This patch adds a ID specific(PCI_VENDOR_ID_FREESCALE & PCI_ANY_ID based)
'early' fixup quirk to replace class code with PCI_CLASS_BRIDGE_PCI as
class. Then the above information disappears.
