Max Staudt 8416dc8bca udev: permanent symlinks with USB revision for /dev/media* ...

As a follow-up in the style of:
  873be895ed ("udev: add USB revision in ID_PATH")
this patch adds a second symlink for media controllers, this time
including the USB revision.

This means that in addition to persistent symlinks like:
  pci-0000:04:00.3-usb-0:1:1.0-media-controller -> ../../media0

We now also get:
  pci-0000:04:00.3-usbv2-0:1:1.0-media-controller -> ../../media0

...which helps distinguish media devices plugged into different USB root
hubs provided by the same PCI card, at least as long as they are for
different USB revisions.

Fixes: 04f19d6735 ("udev: Add /dev/media/by-path symlinks for media controllers")
