fwk: 16-inch: change the battery LED duty when the system state is changed

Decrease PWM duty to reduce side RGB LED power consumption
in S5 for ErP lot3 (<500mW).
White LED set [10,15,10] in S0/S3 and
decrease PWM duty to [6,9,6] in S5.

BRANCH=fwk-tulip-29169
BUG=https://app.clickup.com/t/86eun47uq
TEST=confirm the brightness change of the white LED when powered on/off
