The read and write functions are nearly identical, combine them
and convert to a switch statement. This also makes it easy to
narrow the scope of when we use the io/mem accessors in case new

We can actually handle MMIO and I/O port from the same access function
since PCI already does abstraction of this. The ROM BAR only requires
a minor difference, so it gets included too. vfio_pci_config_readwrite
gets renamed for consistency.

This series make use of the recently posted kernel-side vfio-pci
support for accessing VGA ranges. This enables a handful of devices
to be used as the primary (only) VM console. See patch 2 for a list
of devices. These show seabios text mode output and work with
standard VGA drivers.
Most VGA cards need some kind of quirk to fully operate since they
hide backdoors to get to other registers outside of PCI config space
within the registers, but this provides the base infrastructure. If
we could identity map PCI resources for assigned devices we would need
a lot fewer quirks.
Apparently graphics vendors need to come up with new ways to retrieve
PCI BAR addresses on every revision of their chip. These are the ones
that I've found on the following assortment of cards:
Advanced Micro Devices [AMD] nee ATI Cedar PRO [Radeon HD 5450/6350]

Create two new legacy regions, one for MMIO space below 1MB and
another for 64k of I/O port space. For devices of PCI class VGA
these ranges will be exposed and allow direct access to the device
