It is possible that the OpenSBI config DT node is present but
the "cold-boot-harts" DT property is not present. In this case,
the fw_platform_coldboot_harts_init() will do nothing which
in-turn causes OpenSBI firmware hang at boot time.
To address the above issue, fallback to the default approach
when the "cold-boot-harts" DT property is not present.
