tegra124: Add the tegra124 compatibility string to crossystem.

Teach crossystem the tegra124 compatibility string so that it can identify the
platform for tegra124 based systems.

I called the platform Tegra5 to fit in with what seems to be the naming scheme
for the other Tegra SOCs.

TEST=Built and ran on nyan and saw the "platform_family" setting return Tegra5
instead of (error).
