conf: Get rid of virDomainCapsDevice

The struct contains a single boolean field, 'supported':
the meaning of this field is too generic to be limited to
devices only, and in fact it's already being used for
other things like loaders and OSs.

Instead of trying to come up with a more generic name just
get rid of the struct altogether.
