ARM: tegra: add/edit headers for Tegra124

These headers define the Tegra124 hardware. Add them to the usual
place.

Add Tegra124 chip ID/SKU ID definitions to common headers.

There's no real HW change on Tegra124 for 90% of the toys, so it might
make sense for a future patch to unify some of the content of these
files in a common location.
