This unifies the PWM module interface for LM4 and STM32. Now PWM channels are defined in board.h/board.c. Instead of calling functions named pwm_set_fan_duty(x), one can now use pwm_set_duty(PWM_CH_FAN, x), which prevents additional functions added when we have a new PWM channel. BUG=chrome-os-partner:18343 TEST=Limit input current on Spring. TEST=Check power LED in S0/S3/S5 on Snow. TEST=Check keyboard backlight functionality on Link. TEST=Check fan speed control/detecting on Link.
