The nvidia,tegra210-ahub binding is missing schema for child nodes. This
results in warnings if 'additionalProperties: false' is set (or when the
tools implement 'unevaluatedProperties' support). Add the child nodes
and reference their schema if one exists.

v2:
 - Also add 'dspk' child node

This patch ideally should be applied before this series[1].
