[Qemu-devel] [PATCH v1 12/13] q35: fill in usb pci slots with -usb

[Jason Baron <jbaron@redhat.com>]

From: Jason Baron <jbaron@redhat.com>

This fills out the usb slots on q35, when -usb is passed.
We now have (lspci output):

00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 03)
00:1d.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 03)
00:1d.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 03)
00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03)
