[PATCH v4 0/3] Add Meta: to Metadata devices

[Ricardo Ribalda <ribalda@chromium.org>]

Metadata devices usually companion "real" devices. In order to
distinguish them properly, add the Meta: prefix to their names.

Also, add a unique suffix to all the uvc devices, to multisensor cameras
do not show the same names for all their devices (IR, RBG....).

v4:
- Rebase to latest master

v3:

- Add the meta logic to the core

v2: uvc: Restore old vdev name
