Add subsystemid option to sconfig
Allow user to add 'subsystemid <vendor> <device> [inherit]' to devicetree.cb for PCI and PCI domain devices. Example: device pci 00.0 on subsystemid dead beef end If the user wants to have this ID inherited to all subdevices/functions, he can add 'inherit', like in the following example: device pci 00.0 on subsystemid dead beef inherit end If the user don't want to inherit a Subsystem for a single device, he can specify 'subsystemid 0 0' on this particular device.
