Connect these up so that we can test the hardware.

BUG=b:71902053
BRANCH=none
TEST=manually on EC:
> pwm
PWM channels:
  0: 0%
  1: 100%
  2: 100%
> pwm 1 50
Setting channel 1 to 50
  1: 50%
> pwm 2 50
Setting channel 2 to 50
  2: 50%
> pwm 1 10
Setting channel 1 to 10
  1: 10%

See that the colours changes orange/blue
