If thermal bank with 4 sensors, thermal driver should read TEMP_MSR3.

However, currently thermal driver would not read TEMP_MSR3 since mt8173
thermal driver only use 3 sensors on each thermal bank at the same time,
so this patch would not effect temperature.
Only if mt mt8173 thermal driver use 4 sensors on any thermal bank, would
read third sensor two times, and lose fourth sensor of vale.
