Michael S. Tsirkin 45eb768c70 pci_bridge: factor out common code
Reuse common code in pcie_port, override the hardwired-to-0
bits per PCI Express spec.
No functional change but makes the code easier to follow.

Alex Williamson ba7d8515c1 pci: Teach PCI Bridges about VGA routing
Each PCI Bridge has a set of implied VGA regions that are enabled when
the VGA bit is set in the bridge control register.  This allows VGA
devices behind bridges.  Unfortunately with VGA Enable, which we
formerly allowed but didn't back, comes along some required VGA
baggage.  VGA Palette Snooping is required, along with VGA 16-bit
decoding.  We don't yet have support for palette snooping.
We also don't have support for 10-bit VGA aliases, the default mode, but
we enable the register, even on root ports, to avoid confusing guests.
Fortunately there's likely nothing from this century that requires these
features, so the missing bits are noted with TODOs.

Michael S. Tsirkin c759b24fae pci: fix path for local includes
Include dependencies from pci core using the correct path.
This is required now that it's in the separate directory.
Need to check whether they can be minimized, for now,
keep the code as is.
