t132 display: Add proper guards to display code

Browse source 
Enable display code only if mainboard selects
MAINBOARD_DO_NATIVE_VGA_INIT. Otherwise build breaks for boards that do not
support display init yet.

BUG=chrome-os-partner:31936
BRANCH=None
TEST=Compiles for both rush and ryu. Display comes up for ryu in both normal and
dev mode.
