[PATCH v3] usb: xhci-pci: Add AMD 600 series to xhci-pci-prom21

[Mirko Jechow]

From: Stephen Horvath <linux@xxxxxxxxxxxx>

It seems the xhci-pci-prom21 module only has IDs for the 800 series
chipsets. However, the 600 series chipsets also have Promontory 21
chips, so we should add their IDs to the list as well.

I have tested this on my X670 board featuring DID `0x43f7`.

`1022:43f7` also appears on the PCI ID database
(https://pci-ids.ucw.cz/read/PC/1022/43f7).
Device IDs `0x43f9` (B665) & `0x43fa` (A620) were suggested by Shyam.

Also list the new IDs in Documentation/hwmon/prom21-xhci.rst.
