MLK-17641 thermal: imx: Fix race condition in imx_thermal_probe()

Upstream reports below race condition:

When device boots with T > T_trip_1 and requests interrupt,
the race condition takes place. The interrupt comes before
THERMAL_DEVICE_ENABLED is set. This leads to an attempt to
reading sensor value from irq and disabling the sensor,
based on the data->mode field, which expected to be
THERMAL_DEVICE_ENABLED, but still stays as THERMAL_DEVICE_DISABLED.
Afher this issue sensor is never re-enabled, as the driver state is wrong.

Fix this problem by setting the 'data' members prior to requesting
the interrupts.
