Currently only R-Car H2 uses the new formula, which should apply to all R-Car Gen2/Gen3 SoCs. Gr{oetje,eeting}s, Geert

We could finally measure the clock on an Ebisu board. The new formula gives way better results, i.e. 100kHz instead of 106kHz and 400kHz instead of 387kHz. Switch to these formulas for all Gen3 SoCs.
