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.
