tee: optee: take DT status property into account

Browse Source 
[ Upstream commit db878f76b9 ]

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.
