Refactor PWM module
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.

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.
BRANCH=None
