Rob Herring 5be478f9c2 dt-bindings: Another round of adding missing 'additionalProperties'
Another round of wack-a-mole. The json-schema default is additional
unknown properties are allowed, but for DT all properties should be
defined.

title: Tegra210 ADMAIF Device Tree Bindings
description: |
ADMAIF is the interface between ADMA and AHUB. Each ADMA channel
that sends/receives data to/from AHUB must interface through an
ADMAIF channel. ADMA channel sending data to AHUB pairs with ADMAIF
Tx channel and ADMA channel receiving data from AHUB pairs with
ADMAIF Rx channel.
