thermal: imx_thermal: fix busywait if IMX6 temp <0C

The temperature calculation must be typecasted to keep the compiler
from sign extending a negative value prior to division.

This fixes an issue where if the CPU temperature is <0C it will get stuck
in the busywait loop until the CPU heats up to 0C.
