So, looking at:

    pinctrl: sunxi: add new D1 pinctrl support
    
    For the first time since at least the Allwinner A10 SoCs, the D1 (and
    related cores) use a new pincontroller MMIO register layout, so we
    cannot use our hardcoded, fixed offsets anymore.
    Ideally this would all be handled by devicetree and DM drivers, but for
    the DT-less SPL we still need the legacy interfaces.
    
    Add a new Kconfig symbol to differenciate between the two generations of
    pincontrollers, and just use that to just switch some basic symbols.
    The rest is already abstracted enough, so works out of the box.

Is there some way to abstract things so that again, non-SPL has a single
driver, and for SPL we can just hard-code a few things?
