Preparatory work to use common host command code between ARM and x86. Every command sends back explicitly the size of the response payload. The size of the response defaults to 0 ond can be updated. Add a protocol version number returned as command 0x00 to help with backward compatibility. move a couple of function from lpc specific header to host commands to be able to implement them for the I2C link.

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

src/platform/ec/chip_interface/*.
