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.
