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().
