i2c/ww_ring: use shorter blinking program
The originally loaded blinking program was written to allow gradual
change in LED brightness, which required controlling each LED with its
own engine. In fact there is no need in gradual brightness changes
when the firmware is controlling the ring. This allows to control all
LEDs by one engine, making the code simpler and more robust (no need
to synchronize the three engines any more).
BRANCH=storm
BUG=chrome-os-partner:36059
TEST=verified that recovery boot WW ring patterns work as expected.
