media: uvcvideo: Set unique vdev name based in type

Browse source

[ Upstream commit e3f60e7e1a ]

All the entities must have a unique name. We can have a descriptive and
unique name by appending the function and the entity->id.

This is even resilent to multi chain devices.

Fixes v4l2-compliance:
Media Controller ioctls:
                fail: v4l2-test-media.cpp(205): v2_entity_names_set.find(key) != v2_entity_names_set.end()
        test MEDIA_IOC_G_TOPOLOGY: FAIL
                fail: v4l2-test-media.cpp(394): num_data_links != num_links
	test MEDIA_IOC_ENUM_ENTITIES/LINKS: FAIL
