anahera: Update charging LEDs behavior
This patch updates the LEDs behavior.
Change as below:
1. battery error:
Original - Blinking white quickly. (0.5 sec ON, 0.5 sec OFF)
New - Blinking amber quickly. (0.5 sec ON, 0.5 sec OFF)
2. battery low:
Original - Blinking white slowly on right side led.
(1 sec ON, 1 sec OFF)
New - Blinking amber slowly on both side leds.
(1 sec ON, 1 sec OFF)
BUG=b:208912133
BRANCH=none
TEST=Verify LEDs worked indeed.
