pci: Create and register a new PCI Express TypeInfo

This will allow us to differentiate Express and Legacy buses.

pci: Move PCI and PCIE type defines

Move these so that we can reference them from a more common header
instead of including pci_bus.h everywhere.

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...

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.

pci_bridge: drop formatting from source

We use the same formatting for all files, it
doesn't make sense to have formatting directives only
in pci bridge header.

pci: Fix INTx routing notifier recursion

For some reason we recurse to fire the INTx routing notifier for each
child of a bus, for each possible device of a bus. That means that if
we add a root port, the notifier gets called for that bridge 256
times. If we add an upstream switch behind that root port, 256^2. But...

pci_bridge: Use a default map_irq function

The PCI bridge spec defines a default swizzle for translating INTx
IRQs from secondary bus to primary. Use this by default for any
bridge that doesn't set a function.

pci: refuse empty ROM files

A zero size ROM file is invalid and should produce a warning.
Attempting to use a zero size file ends up hitting an assertion
qemu_ram_set_idstr() because RAMBlocks with duplicate addresses are
allocated - due to zero size the allocator doesn't increment the next...

pci: Add PCI VGA helpers

Allow devices to register VGA memory regions for handling PCI spec
defined VGA I/O port and MMIO areas. PCI will attach these to the
bus address spaces and enable them according to the device command
register value.
