tee: optee: take DT status property into account
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. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org>
