usb: pci-quirks: handle HAS_IOPORT dependency for AMD quirk
In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. In the pci-quirks case the I/O port acceses are used in the quirks for several AMD south bridges, Add a config option for the AMD quirks to depend on HAS_IOPORT and #ifdef the quirk code.
