Improve VIDIOC_G_CHIP_IDENT (better diagnostics)
From: Hans Verkuil <hverkuil@xs4all.nl>
Simplify the VIDIOC_G_CHIP_IDENT implementation by adding a single
common function. The ident can now also return NONE: not found, UNKNOWN:
found, but we don't know what chip it is, and AMBIGUOUS: multiple
chips were matched so the match values were too general.
