[SeaBIOS] [SeaBIOS PATCH 2/2] hotplug: Add device per func in ACPI DSDT tables

[Amos Kong]

Only func 0 is registered to guest driver (we can
only found func 0 in slot->funcs list of driver),
the other functions could not be cleaned when
hot-removing the whole slot. This patch adds
device per function in ACPI DSDT tables.

Have tested with linux/winxp/win7, hot-adding/hot-remving,
single/multiple function device, they are all fine.
