Subject: [PATCH 2/4] dt-bindings: memory: tegra: Add Tegra264 definitions

From: Sumit Gupta <sumitg@...dia.com>

Add memory client ID defines for use by the interconnects property in
the device tree and tegra_mc_client table in the MC driver. Note that
these IDs are defined by the hardware, so the numbering doesn't start
at 0 and contains holes.
