Nice cleanup, thanks!

As a followup, there is some confusion between values of the revision
property (1-4) and PCI device revisions (QXL_REVISION_STABLE_Vxy).  They
are the same right now, but this means that you can do one of the following:

1) if they are always going to be the same, eliminate pci_device_rev
from qxl_init_common, just use qxl->revision instead;

2) if they might diverge, change the value of QXL_DEFAULT_REVISION from
QXL_REVISION_STABLE_V12 to 4.
