The Frequency Hopping Controller (FHCTL) seems to have different versions, as it has a slightly different register layout on some older SoCs like MT6795, MT8173, MT8183 (and others). This driver is indeed compatible with at least some of those older IP revisions, so all we need to do is to add a way to select the right register layout at registration time.
