lib: fdt_domain: Default boot-hart to coldboot HART for multi-domain boot
When "boot-hart" is not specified, dom->boot_hartid was left as -1U,
causing domain context switching to fail. Default it to the coldboot
HART to enable SMP boot in multi-domain setups, consistent with how
next-arg1 is handled.
Also update its description in domain_support.md.
