krane: Use the PWM mode to adjust brightness as lowest
Adjust current=4ma, pwm=1/32, and change the state as: charging is blue charged full is green low battery is red BUG=b:137618886 BRANCH=kukui TEST=Do a full charging test, notice LED indicator status under different charge state Change-Id: Ic1b7a99ab3edaee5c92a5cae56bc6d9a321e9c23 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/1918995 Reviewed-by: Eric Yilun Lin <yllin@chromium.org> Tested-by: Kook Zhang <zhangbinbin@huaqin.corp-partner.google.com> Commit-Queue: Leo Zhou <zhoubo@huaqin.corp-partner.google.com>
