dm: core: Add address translation in fdt_get_resource

Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.
