This patch serie adds support for thermal monitoring block on Qualcomm's
PMIC5 chips. PM8150{,b,l} and sm8250-mtp board device trees are extended
to support thermal zones provided by this thermal monitoring block.
Unlike the rest of PMIC thermal senses, these thermal zones describe
particular thermistors, which differ between from board to board.
Changes since v1:
- Introduce fixp_linear_interpolate() by Craig Tatlor
- Lots of syntax/whitespace changes
- Cleaned up register definitions per Jonathan's suggestion
- Implemented most of the suggestions from Bjorn's and Jonathan's
review
