spi: dt-bindings: cdns,qspi-nor: Add Renesas RZ/N1D400 to the list 



Add support for the Renesas RZ/N1D400 QSPI controller.

This SoC is identified in the bindings with its other name: r9a06g032.
It is part of the RZ/N1 family, which contains a "D" and a "S"
variant. IPs in this SoC are typically described using 2 compatibles:
the SoC specific compatible and the family compatible. The original
Cadence IP compatible is dropped because it is unusable on its own.

Indirect accesses are not supported by this flavour of the Cadence IP,
which means several properties have no meaning in the scope of the
Renesas compatible. Let's make sure they are no longer expected nor
mandatory.
