Add boolean input argument @no_map to helper function fdtdec_add_reserved_memory() to add or not "no-map" property for an added reserved memory node.
Property no-map is used by the Linux kernel to not not map memory in its static memory mapping. It is needed for example for the| consistency of system non-cached memory and to prevent speculative accesses to some firewalled memory.
No functional change. A later change will update to OPTEE library to add no-map property to OP-TEE reserved memory nodes.
