Subject: [PATCH] pci: Add definition for USB Device Controller PCI Class ID
PCI-SIG has defined Interface FEh for Base Class 0Ch,
Sub-Class 03h as "USB Device (not host controller)". It is
already being used in various USB device controller drivers
for matching, so converting those to use the definition.
