Homestar:LED:Add LED behavior
The led behavior define as following:
Power Led behaiver:
1.S0, Green (soild on)
2.S3, Orange (1s on 3s off)
3.S5, off
Battery Led behaiver:
1.Red on S0/S3/S5, battery capa < 5%
2.Orange on S0/S3/S5, 5% < battery capa < 97%
3.Green on S0/S3/S5, battery capa > 97%
4.Battery error: Red on 1sec off 1sec
5.Factory test: Red on 2sec, Green on 2sec
BUG=b:187539586
TEST=make -j BOARD=homestar
Verify build on EVT board
Make sure ectool led battery red/green/amber/off/auto work correctly.
