[PATCH v4 02/10] of: reserved_mem: dedup and relocate reserved-memory messages

From: Wandun Chen <chenwandun at lixiang.com>

In both fdt_scan_reserved_mem and fdt_scan_reserved_mem_late, there
are identical check-related print messages. Consolidate these messages
by moving them all into the fdt_scan_reserved_mem function.

No functional change.
