mkimxboot: rewrite dualboot
Rewrite dualboot in C code instead of assembly. Also properly handle subtarget and simply Makefile. This should make the dualboot stub more readable and easier to extend. The new code also gracefully handles power up from RTC alarm on imx233. Change-Id: I7c225254b1463a97e76b6cb4de476aa2d2c9d2f9
