[Why]
Creating the prop uses UNKNOWN as the initial value, which is not a
supported value if the prop is to be supported.
[How]
Set the panel orientation default value to NORMAL right after creating
the prop if no DSI panel exists.
Panels have their own orientations, and panel orientation can't be
overriden once initialized to a value.
v1:
Set panel orientation only if DSI panel does not exist.
