Add Tegra264 ADMA support to the device tree bindings documentation.
The Tegra264 ADMA hardware supports 64 DMA channels and requires
specific register configurations.

The binding maintains compatibility with existing Tegra platforms
while adding support for Tegra264-specific features.

This is confusing sentence, because you did not make anything compatible
there. Drop it.

This is incomplete, missing constraints. Read *ENTIRE* binding, not top
25 lines only.
