[PATCH] fbdev: tag by scantype in sysfs

Modify the sysfs description of a video mode such that modes are tagged with
their scan type, (p)rogessive, (i)nterlaced, (d)ouble scan.  For example,
U:1920x1080i-50.  This is useful to disambiguate some of the 'consumer' video
timings found in CEA-861 (especially those for EDTV).
