vga_pci: Improve vga boot display detection.
* Check the "VGA Enable" bit on the parent bridge only if it is a
PCI-to-PCI bridge.
* Always check the "I/O" and "Memory address space decoding" bits on the
video card itself.
* Furthermore, vga_pci_attach() logs "Boot video device" if the card
being attached is the Chosen One:
vgapci0: <VGA-compatible display> [...]
vgapci0: Boot video device
This is FreeBSD's r259579.
