I have mixed feelings about this patch, as (AFAIK) there is no such
thing as a Gray Hawk CSI/DSI sub-board, so at least the comment
should be fixed.

However, it does make sense to make things as similar as possible to
White Hawk (Single).  In the end, I do hope to share most of the
White/Gray Hawk (Single) DTS.  Of course we have to cater for the
small differences like the use of a C-PHY vs. D-PHY, which is one
difference I hadn't realized before.

What do other people think?
