dvdspu: do not clear out high bits from display area

http://dvd.sourceforge.net/spu_notes does not mention that high bits
are to be masked, and not clearing them makes a sample work, where
clearing them yielded left > right.
History does not shed any light, as tracing this code's origin shows
the same bitmasks being there in 2007 when it was imported.
