of: reserved-memory: ignore disabled memory-region nodes
Ignore disabled nodes in the memory-region
nodes list and continue to initialize the rest
of enabled nodes.
Check if the "reserved-memory" node is available
and if it's not available, return 0 to ignore the
"reserved-memory" node and continue parsing with
next node in memory-region nodes list.
