[PATCH 3/3] tests: p2p: verify that changing p2p_disabled removes/adds P2P device

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

Add a test to verify that if p2p_disabled is changed on the (possible)
parent device for a dedicated P2P device, then the dedicated P2P device
is added or removed as appropriate.
