Add subsystemid option to sconfig

Browse Source 
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.
