Slightly update the host commands API

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.
