[SeaBIOS] [PATCH 2/2] boot: allow multiple hard drives in the boot list

[Julian Stecklina]

The current code is limited to having a single hard drive in the list
of devices that are probed for boot. Allow adding multiple hard drives
by adding each of them in the list of boot devices and passing along
their ID.
