This patch does not change anything functionally, just cleans up
the DP compliance related variables and stores them all together
in a separate struct intel_dp_compliance. There is another struct
intel_dp_compliance_data to store all the test data. This makes it easy to
reset the compliance variables through a memset instead of
individual resetting.
v2:
* Removed functional changes for EDID (Jani Nikula)
