thermal/driver/qoriq: Workaround unexpected temperature readings from tmu
Invalid temperature measurements may be observed across the temperature
range specified in the device data sheet. The invalid temperature can
be read from any remote site and from any capture or report registers.
The invalid change in temperature can be positive or negative and the
resulting temperature can be outside the calibrated range, in which
case the TSR[ORL] or TSR[ORH] bit will be set.
Workaround:
Use the raising/falling edge threshold to filter out the invalid temp.
Check the TIDR register to make sure no jump happens When reading the temp.
