mb/google/brox: Hint romstage init about upcoming reset

Add support for the mainboard to check for any potential firmware
component update and hence the assosicated reset. This indication can be
used to avoid any redundant resets during the boot flow.

BUG=b:375444631
TEST=Build Brox BIOS image and boot to OS. Ensure that the hints are
provided correctly and 2 redundant resets are filtered out.
