This patch adds support for calculating v4l2_bt_timings based on
CVT and GTF standards. The timings are calculated for a given
standard, CVT or GTF using a set of parameters- width, height,
refresh rate and flags like whether it is an interlaced format,
and whether to use reduced blanking.

In addition to v4l2_find_dv_timings_cap(), where timings are serached
against the list of preset timings, the incoming timing from v4l2-ctl
is checked against CVT and GTF standards. If it confirms to be CVT or
GTF, it is treated as valid timing and vivid format is updated with
new timings.
