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.
Change since V1:
1. Update commis message
a. Add Reviewed-by: Matthias Brugger <matthias....@gmail.com>
b. Add tag Fixes: b7cf0053738c ("thermal: Add Mediatek thermal driver for
mt2701.")
