Subject: [PATCH v3 00/16] Another round of tsens cleanups

This is another series of tsens cleanups before we add interrupt support. This applies on top of 4.19-rc2.

Patches [1-6] can directly be applied by Eduardo.
Patches [9-16] can directly be applied by Andy.
Patches [7-8] introduce a new check and needs review and can then be
applied completely separately by Eduardo. 

There is a *dependency* however. Patch 1 should be applied to the tree
before the DT changes in patches 9 and 10.

In this series, I've collected all outstanding tsens patches by combining
the patches from the v2 posting with 3 DT patches for sdm845 thermal zones
and msm8916 camera and gpu thermal zones. Details are as follows:

- splitup 8916 and 8974 register address spaces for SROT and TM
- cleanups: move to spdx, dead code removal, removal of id field
- Add support to map the SROT address space for DTs that list it separately
- Check if TSENS IP is enabled in firmware by querying the SROT space
- Add myself as maintainer of tsens
- Add one-off patches adding sdm845 thermal zones and msm8916 gpu and
  camera thermal zones to this series.

Changes since v2:
- Split up changes to code and dt and within dt, split into arm and arm64
  patches
- Rearrange the sequence of patches so that the thermal maintainer can pick
  up the first part and the platform maintainer can pick up the latter part
  of the series
- Drop patch 09/11 because it causes some issues on systems with
  non-contiguous enabled sensors e.g. db410c
- Drop patch 10/11 because reg-name property isn't encouraged
- Fix a bug on msm8916 to check if IP is enabled in firmware. This was due
  to the register being at a different offset on msm8916. Fixed by coding
  this information as private data.

Changes since v1:
- Split up changes that split the address space and added qcom,sensors
  property into two separate patches
- Remove brackets in typo correction patch
