Subject: [PATCH 01/23] ARM: OMAP: remove DSS DT hack

As a temporary solution to enable DSS for selected boards when booting
with DT, a hack was added to board-generic.c in
63d5fc0c2f748e20f38a0a0ec1c8494bddf5c288 (OMAP: board-generic: enable
DSS for panda & sdp boards).

We're now adding proper DT support, so the hack can be removed.
