Add devicetree compatible and match data for "mediatek,generic-tphy-v3" in the MediaTek TPHY driver.
According to the Linux driver implementation, the only difference between this and v2 is that v3 doesn't need to set slew rate. There is one register write in the U-Boot driver that gets skipped because of this now. Also, according to the upstream devicetree bindings, mt8195 is also v3 TPHY, so it gets updated as well.
