I'd like a comment here to explain what PIPE_EDP_OFFSET
actually means. Eg.:
/*
* There's actually no pipe EDP. Some pipe registers have
* simply shifted from the pipe to the transcoder, while
* keeping their original offset. Thus we need PIPE_EDP_OFFSET
* to access such registers in transcoder EDP.
*/

Why is there a separate offset for these? They're all within the
normal transcoder range, aren't they?
