tegra132: Pass panel spec to lib_sysinfo
panel spec such as resoultion, bits per pixel are needed to pass to depthcharge/payload for displaying bitmap onto panel. Enable display code only if mainboard selects MAINBOARD_DO_NATIVE_VGA_INIT. Otherwise build breaks for boards that do not support display init yet. BRANCH=none BUG=chrome-os-partner:31936 TEST=Compiles for both rush and ryu. Display comes up for ryu in both normal and dev mode.
