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.

It would be nice to update all the newly added device IDs to the kernel
documentation as well.

Initially, `Documentation/hwmon/prom21-xhci.rst` has added the following
line:
PCI IDs: 1022:43fc, 1022:43fd
It would be more appropriate to add these new IDs into the same line, or
just drop the deprecated document line.
