[PATCH v3 01/16] dt-bindings: remoteproc: k3-dsp: Add the L2 auxiliary and DRU regions

[Tomeu Vizoso]

Besides the existing L2 SRAM region, at least some C7x DSPs in K3 SoCs
have an additional region called in the documentation "AUX L2 SRAM".
This is just some more SRAM that is accessed separately.

Also add the memory region for the control registers of the DRU (Data
Routing Unit), which allow starting DMA transactions and polling for
their completion.

The two entries are optional, so existing device trees still validate,
and are allowed only for the ti,am62a-c7xv-dsp compatible, the C7x
generation that has them.
