media: Revert "media: uvcvideo: Set unique vdev name based in type"
commit f66dcb32af19faf49cc4a9222c3152b10c6ec84a upstream.
A lot of userspace depends on a descriptive name for vdev. Without this
patch, users have a hard time figuring out which camera shall they use
for their video conferencing.
This reverts commit e3f60e7e1a2b451f538f9926763432249bcf39c4.
