Re: [PATCH v2] usb: xhci-pci: Add AMD 600 series to xhci-pci-prom21

Tested on an MSI MPG X670E Carbon WiFi (Ryzen 9 7950X3D). The board exposes two 600 series chipset xHCI functions, 1022:43f7 at 13:00.0 and 15:00.0 -- X670E is built from two Promontory 21 dies.

Without the patch neither function creates an auxiliary device, so prom21-xhci has nothing to bind to and the sensor is unavailable. With it applied to 7.2.3, both functions bind xhci-pci-prom21, both auxiliary devices appear, and both dies report:

  prom21_xhci-pci-1300  temp1: +57.4 C
  prom21_xhci-pci-1500  temp1: +62.8 C

k10temp Tctl read +58.0 C at the same moment, so the conversion derived on 800 series silicon looks right here too.

USB is unaffected: the devices behind both controllers enumerate normally and the log shows no new xHCI errors after they moved to the glue driver.
