make main() in snow's romstage.c our romstage entry point
Our earlier attempt was jumping straight from asm to the old u-boot board_init_f in lowlevel_init_c.c. We are getting ready to transition to using a real bootblock for ARM, so add romstage.c to the files compiled and we'll make main() our entry point. This also updates romstage.ld to place main() (*(.text.startup)) at the beginning of romstage.
