Right now we set explict base addresses for the PCI IO regions in the VMware

map the physical memory.

The problem is, the addresses we're setting in the BAR is not taken into
account in the e820 mapping.

Actually, it looks like the e820 map is okay, but I do get some errors in the gust about remapping that range so I do think this patch is correct.

This patch removes the explicit BARs and registers the second region through
the normal PCI code.

I've only tested with a Linux guest and the open source VMware VGA driver.

This patch needs -p2 to apply against the QEMU CVS tree.
