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.
