tegra: move to common SPL framework
Change tegra SPL to use common SPL framework. Any tegra specific initialization is now done in spl_board_init() instead of board_init_f()/board_init_r(). Only one SPL boot target is supported on tegra, which is boot to RAM image. jump_to_image_no_args() must be overridden on tegra so the host CPU can be initialized.
