The thermal code uses int, long and unsigned long for temperatures

to positive temperatures without need. 'long' is 64bit on several
architectures which is not needed. Consistently use a plain 'int'
for temperatures.

It looks like some longs remain in db8500_thermal.c, int340x_thermal/*,
intel_soc_dts_thermal.c, kirkwood_thermal.c, rockchip_thermal.c and 
samsung/exynos_tmu.c. (found by 'grep -R long drivers/thermal/*)
