tee: optee: take DT status property into account
[ Upstream commit db878f76b9ff7487da9bb0f686153f81829f1230 ] DT nodes may have a 'status' property which, if set to anything other than 'ok' or 'okay', indicates to the OS that the DT node should be treated as if it was not present. So add that missing logic to the OP-TEE driver.
