[PATCH 3/5] ARM: dts: keystone-k2e: Add MSM RAM node

[Suman Anna]

Add the RAM managed by the Multicire Shared Memory Controller (MSMC)
as a mmio-sram node. The Keystone 2 Edison SoC has 2 MB of such
memory. Any specific MSM memory range needed by a software module
ought to be reserved using an appropriate child node.
