TISCI API reported msmc_size, does not include 64KB reserved size for tifs aka MSMC comms memory, see documentation[0]. As part of fixup, original code uses TISCI API reported msmc_size as size for SRAM DT node. tifs node is similar to l3-cache, which should hold address above msmc_size, and should be deleted before passing control to OS.
