commit c46dedbb1ca0ff828c5868b640ff293c4d4ae030

tegra132: implement platform_prog_run()

The tegra132 SoC is currently booting up on the AVP cpu which
    bootstraps the rest of the SoC. Upon exiting romstage it
    runs ramstage from its faster armv8 core. Instead of hard
    coding the stage loading operations use run_ramstage().
