thermal: intel: Fix unsigned comparison with less than zero

Browse source 
[ Upstream commit e7fcfe67f9f410736b758969477b17ea285e8e6c ]

The return value from the call to intel_tcc_get_tjmax() is int, which can
be a negative error code. However, the return value is being assigned to
an u32 variable 'tj_max', so making 'tj_max' an int.

Eliminate the following warning:
./drivers/thermal/intel/intel_soc_dts_iosf.c:394:5-11: WARNING: Unsigned expression compared with zero: tj_max < 0
