[PATCH v2 5/5] dt-bindings: soc: ti: omap-iva: Document DSP child node

[Eduard Bostina <egbostina@gmail.com>]

Document the DSP child node in the IVA schema to resolve dtbs_check
warnings.

OMAP3 device tree (omap3.dtsi) models the DSP as a child of the
IVA subsystem. This node was missing from the old iva.txt binding.
Add it to align the schema with current ABI usage.
