lcd: Remove HAVE_VIEWPORT_CLIP

Browse source 
This was only enabled for the mrobe500 and sansaconnect targets.
Most targets are therefore running without this "safety" measure,
and presumably we'd have noticed long ago if there was a problem.
So in all likelihood this is just a bunch of dead code that we
don't need to carry around.
