staging: olpc_dcon: drop XO-1.5 support for now

The vx855 stuff isn't upstream yet; for now, drop support for XO-1.5.
This will come back once the 1.5 code is in place (and will be in a form
that allows both 1.0 and 1.5 support to be compiled in at the same time),
but for now just remove it.  This is necessary to get the driver building.
