Pass the actual msg_len instead of the maximum outbound message size. BUG=none TEST=tested on daisy using logic analyzer (notes below) Beforehand, the output on a logic analyzer looked sane until the last bits and stop condition, after which the bus appeared to go haywire and the system would reset. I'm guessing that this is due to the EC trying to drive SDA line while the host is holding SCL high.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

---- chip interface ---- The interface is defined in
src/platform/ec/chip_interface/*.
