This patch adds a driver for my shared memory PCI device using the uio_pci
interface.  The driver has three memory regions.  The first memory region is for
device registers for sending interrupts. The second BAR is for receiving MSI-X
interrupts and the third memory region maps the shared memory.  The device only
exports the first and third memory regions to userspace.

This driver supports MSI-X and regular pin interrupts.  Currently, the number of
MSI vectors is set to 4 which could be increased, but the driver will work with
fewer vectors.  If MSI is not available, then regular interrupts will be used.

There is now a generic PCI 2.3 driver that can handle all PCI devices. It doesn't support MSI, but if we add MSI support then it can be used without the need for a specialized driver.
