> This introduces a simpler and generic method for for finding (and mapping)
> the TBIPA register.
> Instead of relying of complicated logic for finding the TBIPA register
> address based on the MDIO or MII register block base
> address, which even in some cases relies on undocumented shadow registers,
> a second "reg" entry for the mdio bus devicetree node specifies the TBIPA
> register.
> Backwards compatibility is kept, as the existing logic is applied when
> only a single "reg" mapping is specified.
