This is bit 0.

This section is the only difference from 8996, but this register is
identical to 8996 and 8998. So I think you should add this to
tsens-8996.c and we can use that for 8996, 8998 and sdm845.
Perhaps we should name it tsens-v2, as that seems to be the common
denominator for these, according to the documentation.
