nitrogen6x: display use I2C detect for HDMI
The HPD pin and RX_SENSE registers have proven to be less reliable than using I2C on the EDID pins for detection of an HDMI monitor. In particular, when the HDMI output is reset through a "reboot" cycle, the detect_hdmi() routine often bounces, resulting in a failure to detect a connected monitor.
