old head: 11d60eaa36f9472dca83833070fd2d1b4714fb6b
new head: 654dc4bfabac752ddf61e5e55db77800dfccd531
----------------------------------------------------------------------------
60b7d1d: Add i2c DP AUX communication calls
* remove posix return
* pass GPIO hwLine through vs connector index
* variable scope cleanup
* make lowest level dp aux AtomBIOS call static, non-public
as it is always called by connector code
7a13bce: More work towards DP support.
* add DPBridge encoder flag and set during connector detection
* if external bridge found, do external DDC setup
* pass connectorIndex vs displayIndex to encoder_*_setup
* some of the DP AUX channel stuff should go into accelerant
common code some day like i2c.

More work towards DP support.
* add DPBridge encoder flag and set during connector detection
* if external bridge found, do external DDC setup
* pass connectorIndex vs displayIndex to encoder_*_setup
* some of the DP AUX channel stuff should go into accelerant
common code some day like i2c.
