edid-decode: various fixes
1) Drop an obsolete and always false test in print_standard_timing 2) Drop a test for image width/height where one of the two is 0. 3) Simplify rate test in cta_hf_scdb() (rate is always > 0) 4) Fix Dolby Vision bit for global dimming (0x04 instead of 0x02) Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Reported-by: val.zapod.vz@gmail.com
