Richard Hughes 8fdefd459b pci-bcr: Read the PCI BCR config register from userspace 
We can read this from userspace even when SB is turned on and with the kernel
locked down. The kernel securityfs patches are still in-progress, but will take
significant time to get upstream.

The kernel patches are needed when the PCI device is hidden from userspace.
