Sorry, don't want to more warnings to the file while we are working
constantly to reduce warnings on the other side. There are 3 options

a) Propose fix to dtc
b) Minimally describe second port (DSI) and it keep disabled as its
unusable currently (this more closely describes the HW and the reason
why port indexing is needed in first place)
c) Go back to v9 and describe second port once DSI supported is added in
future,
