thermal: qoriq: Embed per-sensor data into struct qoriq_tmu_data

Embed per-sensor data into struct qoriq_tmu_data so we can drop the
code allocating it. This also allows us to get rid of per-sensor back
reference to struct qoriq_tmu_data since now its address can be
caluclated using container_of().
