This is a v4 patch-set.

There are lots of failure items while running HDCP CTS using UNIGRAF
DPR-100.
In Order to fix those failures, HDCP flow needs to be changed.

The DisplayPort AUX protocol supports I2C transport.
In Order to support MCCS via the aux channel, the aux-i2c operation is
added.

v3 ->v4:
	-split changes into patches.

v2- > v3:
	-split aux read  KSV function to a patch.
	-[1/3] new in v3
	-[2/3] add description of patch

v1 -> v2 :
	- ignored.
