ARM: dts: artik10: change DDC linesubmit/tizen/20160920.051702accepted/tizen/common/20160920.132119
This patch enables gpio-i2c to read EDID correctly. We decided to use gpio-i2c
instead of using hsi2c3. Hsi2c3 worked well in most cases except UDTV and monit
or. We are working on finding out the reason of the failure of hsi2c3.
