scmi: translate the resource only when livetree is not activated
Call the translation function on the ofnode_read_resource result only when the livetree is not activated. Today of_address_to_resource() calls ofnode_read_resource() for livetree support and fdt_get_resource() when livetree is not supported. The fdt_get_resource() doesn't do the address translation so when it is required when livetree is activated but this address translation is already done by ofnode_read_resource().
