pci: clarify configuration access capability rules
The point of the configuration access capability is to enable
access to other capabilities. The intent never was to allow
writes to a random place within device BARs.
Limiting drivers simplifies devices - and devices can always
add another capability if drivers ever want to access
some other range.
This resolves VIRTIO-145.
