[PATCH] thermal: int340x: check for sensor when PTYP is missing

[Srinivas Pandruvada]

For INT3403 sensor PTYP field is mandatory. But some platforms didn't
have this field for sensors. This cause load failure for int3403 driver.

This change checks for the presence of _TMP method and if present, then
treats this device as a sensor.
