docs: Stipulate register 13 must be written last when writing a response

Writes to register 13 (Response Code) are what is used to generate an
interrupt to the host. On receiving this interrupt the host can start
processing the entire response message. Thus to ensure that the host
is processing the correct mbox response register 13 must be the last
to be written.

Stipulate in the protocol documentation that the last register to be
written by the BMC when writing a response must be the response code
into register 13.
