V4L/DVB (8123): Add support for em2860 based PointNix Intra-Oral Camera
em28xx-cards.c
em28xx-input.c
em28xx-video.c
em28xx.h
- Add support for the PointNix Intra-Oral Camera, which required addition of
a construct for reading the "snapshot" button (provided on the em2860 and
em2880 chips, but this is the first case where I have seen it actually used
in a product). The button is wired to pin 56 on the em2880.

Thanks to Roberto Mantovani <rmantovani@libero.it> for testing the changes
