Capability Version (capability_version):
PCI Express Capability is Compliant with Version 1.0 of the PCI Express Spec.
Note:
This capability structure is not compliant with Versions beyond 1.0, since they 
require additional capability registers to be reserved. The only purpose for this 
capability structure is to make enhanced configuration space available. 
Minimizing the size of this structure is accomplished by reporting version 1.0 
compliancy and reporting that this is an integrated root port device. As such, 
only three Dwords of configuration space are required for this structure.
