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.
