drm/amd/display: add aux i2c event log.

[Why]
support i2c transition event log

[How]
refined aux REQ and REP events in aux flow.
commented REQ and REP events in i2c flow.

note: i2c event log is currently commented out. more work is required
to find an portocol parser to and generate event for the parser
