staging: olpc_dcon: add config options for XO_1 and XO_1_5, drop hardcoded XO-1 stuff
This adds CONFIG_FB_OLPC_DCON_1 and CONFIG_FB_OLPC_DCON_1_5 options for
allowing selection of XO-1 and/or XO-1.5 DCON support. In the process,
it also forces the xo_1.c and xo_1_5.c files to build as separate units,
correctly selects between XO-1 and XO-1.5 at runtime, and adds some
hacks to allow xo_1_5.c to build.
This isn't the cleanest patch, but it'll get better as more global
variables are dropped.

Add support for the OLPC XO DCON controller. This controller is
only available on OLPC platforms. Unless you have one of these
platforms, you will want to say 'N'.
