PATCH v2 1/1 arm64: dts: add device tree for ARM SMM-A53x2 on LogicTile Express 20MG

Add a DTS file for the MP2 Cortex-A53 Soft Macrocell Model implemented on a LogicTile Express 20MG (V2F-1XV7) daughterboard. This is based on the version that's currently available from the ARM DTS repository [1].

Changes in v2:
- Remove enable-method and cpu-release-addr from the second CPU (since the Boot Monitor can add those itself).

... and so it does with memreserve on cpu-release-addr.
