So if the transmitted message is CEC_MSG_INITIATE_ARC and the remote side replied with CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED, then a msg->reply value of CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED will match either reply. I thought about either adding a second reply2 field, but that's ugly for all other messages that have only one reply, and what if in the future a new message is added that can have three replies? Another option would be to add a cec_msg flag, but really, the combination of CEC_MSG_REPORT_ARC_INITIATED and a reply value of one of the two possible replies already functions as a flag. Another advantage of this approach is that it is safe to re-use a cec_msg struct. No need to zero a flags field or a reply2 field. So since this really is an exception in the CEC specification, I decided to implement it as an exception as well.

The main difference between Exynos 5433 and earlier is addition of new clocks that have to be controlled.
