Add the RAM managed by the Multicore Shared Memory Controller (MSMC)
as a mmio-sram node. The 66AK2G SoCs have 1 MB of such memory. Any
specific MSM memory range needed by a software module ought to be
reserved using an appropriate child node.

v2: No code changes, SoC name in commit message corrected to use 66AK2G
