Add internal PCI bridge support for the r9a06g032 SOC. The Renesas
RZ/N1D (R9A06G032) internal PCI bridge is compatible with the one
present in the R-Car Gen2 family.
Compared to the R-Car Gen2 family, it needs three clocks instead of
one.

The 'resets' property for the RZ/N1 family is not required since
there is no reset-controller support yet for the RZ/N1 family.

Please drop the "usb_" prefixes.

With the above fixed:

This should be better within allOf block. It's likely that it will be
extended later.
