This small series enables vPCI to filter which PCI capabilites we expose to a
domU. This series adds vPCI register handlers within
xen/drivers/vpci/header.c:init_bars(), along with some supporting functions.
Note there are minor rebase conflicts with the in-progress vPCI series [1].
These conflicts fall into the category of functions and code being added
adjacent to one another, so are easily resolved. I did not identify any
dependency on the vPCI locking work, and the two series deal with different
aspects of emulating the PCI header.
Future work may involve adding handlers for more registers in the vPCI header,
such as STATUS, VID/DID, etc.
