mboxd: Implement timeout return value in GET_MBOX_INFO

The previous patch added a new return field in GET_MBOX_INFO called
"suggested timeout" to be used to provide a suggested maximum timeout
value to the host.

Add this to the return arguments of GET_MBOX_INFO.

Note that the host is free to ignore the value and the daemon can
leave this blank if it doesn't want to provide a timeout.

We hard code a milliseconds per megabyte value which was determined
to be approximately 8000 based on testing and is close to linear
as the access size changes. Testing was conducted on an Aspeed ast2500
on a Witherspoon with the dev-4.7 OpenBMC branch.
