If the command does not respond the driver should not wait for
it to complete before returning.
Tested with SMI debug enabled to ensure that the final command
does not report a failure.

The Google "Wilco" Embedded Controller is a new embedded controller that
will be used in some future devices. The mailbox interface is simliar
to the existing Chromium EC protocol version 3, but not close enough
that it was convenient to re-use the full Chrome EC driver.
This commit adds the basic mailbox interface for ramstage which will be
used by future commits to send varous mailbox commands during the boot
process. The IO base addresses for the mailbox interface are defined in
Kconfig so they can be changed by the mainboard if needed.
