The code is ogranazed in a way that all related parts to the certain platform quirk go toghether. This is not the case for AMD NAVI. Shuffle code to make it happen. While at it, drop the frequency definition and use hard coded value as it's done for other platforms and add a comment to the PCI ID list.
