Before, we calculate the pwm duties for cpu cores and centerlogic by hand, adding pwm_regulator.c to handle this. The default pwm design min/max voltage may be different between revs. With the pwm regulator, this patch changes the little cpu frequency from 600M to 1512M, and raises CPU voltage to 1.2V correspondingly. This also means we decide to drop the ES1 because it may fail to bootup with 1.5G ~ 1.2v.
