tegra: add new target
New target introduces initial support for NVIDIA Tegra SoC based devices.
It focuses on Tegra 2 CPUs, for successors supporting NEON instruction
set the target should be split in two subtargets.
This initial commit doesn't create any device image, it's groundwork
for further additions.
