We recently changed the way host messages are passed to the EC to make it
work nicer across I2C. When we did, we updated all the internal structs
except those used for lightbar commands. This CL updates the lightbar
commands too.
BUG=chrome-os-partner:11277
BRANCH=all
TEST=manual
This shouldn't change anything, but you can ensure that by poking at the
lightbar manually. On Link, run this from a root shell:
ectool lightbar seq stop
ectool lightbar 4 ff 00 ff
ectool lightbar seq run
With the first command, the lightbar pattern should freeze.
With the second command, it should turn magenta.
With the third command, it should resume pulsing as before.

I keep getting asked to build an EC image to manually control the lightbar
patterns so that the Powers That Be can look at it. This change just makes
it possible to turn that mode on and off for yourself. You'll need a root
shell or the EC console to do it, though.
BUG=chrome-os-partner:8039
BRANCH=link
TEST=manual
From the EC console, type
lightbar demo 1
OR from the root shell run
ectool lightbar demo 1
After that, these keys should change the lightbar appearance (transitions
may be slow and subtle - that's intended):
UP = battery is more fully charged
DOWN = battery is less fully charged
RIGHT = battery is charging
LEFT = battery is discharging
BRIGHT = increase lightbar brightness
DIM = decrase lightbar brightness
Note that this does not interfere with the normal function of any keys. It
only adds some additional EC behavior.

Both EC and ectool are still backwards-compatible to the old interface.
BUG=chrome-os-partner:11275
TEST=manual
From U-boot prompt: mkbp hash // test old host talking to new EC
From root shell: ectool echash // test new host talking to new EC
You can also update just the OS and use an old EC, and verify that
'ectool echash' still works, which tests a new host talking to an old
EC.

This is more compatible with kernel and u-boot, and will make it
easier to share code between the ec project and those.
