of: fix incorrect device creation for reserved memory nodes
The current global search for nodes in reserved_mem_matches can find
nodes outside "/reserved-memory". These nodes might not have actual
memory reserved (via memblock), leading to drivers (e.g., ramoops)
accessing unreserved memory and causing memory corruption.
Restrict the scan to the "/reserved-memory" node to ensure created
devices are correctly backed by reserved memory. This enforces
specification compliance and avoids dangerous probing.
