[PATCH 3/7] staging: most: v4l2-aim: assign unique names to devices

[Christian Gromm]

The current V4L2 AIM implementation assigns to all video devices and to
all V4L devices the same names.

This patch makes use of hardware dependent names for the video devices and
allows the user to choose the names for the V4L devices.
