poppy/soraka: Basic LED support
This applies the simple rule: Charging port led is on, other
is off. When charging, LED is amber, otherwise it's white.
Open questions:
- Do we want blinking on low battery? On which side(s)? In
which AP states?
- No blinking in S3? That's ok?
- Need to add led blinking support for special debug mode
- Recovery mode blinking does not work as LED is powered from
a rail that is not on when AP is in S5.
BRANCH=none
BUG=b:37970194
TEST=Charge from one side, led is first amber, then white when
battery is full. Switch side, led behaves the same way.
