i2c/ww_ring: define display pattern programs
Add compiled lp55231 code snippets to allow display certain patterns
when booting the device with the recovery button pressed.
As soon as the press is detected, the low intensify solid white
pattern is enabled. Holding recovery button long enough causes the
device transition between the wipeout requested and recovery requested
states, with the appropriate changes in the displayed pattern.
The patch also includes the source code for the LED controller as well
as instructions on how to compile and modify the code to result in
different colors, intensities, blink periods and duty cycles.
BRANCH=storm
BUG=chrome-os-partner:36059
TEST=reboot an SP5 device with the LED ring attached, keep the
recovery button pressed, observe the changes in the LED display
pattern while the device progresses through the boot sequence.
