Multiple ADMA Channel page hardware support has been added from
TEGRA186 and onwards. Update the DT binding to use any of the
ADMA channel page address space region.

This is v2 but no changelog, no explanation whatsoever... I assume
feedback was not implemented, so please go back to previous version and
address the feedback and then send proper new version with changelog.

See submitting patches.

Best regards,
Krzysztof

It's my bad to not include the changelog info, though I have taken care 
of the feedback on the ADMA DT bindings. I will include the changelog 
info and resend the v2.
