Add PCI_DEVICE_ID_AMD_19H_M60H_ROOT to id_table

This was required for my system (Ryzen 7950x desktop) to load the ryzen_smu device driver.

The device ID was found by looking at lspci -v and matching it with the list in https://github.com/torvalds/linux/blob/master/arch/x86/kernel/amd_nb.c#L18. I think we may need to add the other entries in there as well, but I'm not knowledgeable enough about this to determine that.
