thermal: qoriq: Pass data to qoriq_tmu_calibration() directly
We can simplify error cleanup code if instead of passing a "struct
platform_device *" to qoriq_tmu_calibration() and deriving a bunch of
pointers from it, we pass those pointers directly. This way we won't
be force to call platform_set_drvdata() as early in qoriq_tmu_probe()
and need to have "platform_set_drvdata(pdev, NULL);" in error path.
