TSENS IP v2.x supports critical interrupts and v2.3+ adds watchdog support
in case the FSM is stuck. Enable support in the driver.

This series was generated on top of linux-next from 20200130 to integrate
some patches that that are queued currently.

Changes from v3:
- Remove the DTS changes that are already queued
- Fix review comments by Bjorn
- Fixup patch description to clarify that we don't use TSENS critical
  interrupts in Linux, but need it for the watchdog support that uses the
  same HW irq line.
- Separate kernel-doc fixes into a separate patch.

Changes from v2:
- Handle old DTBs w/o critical irq in the same way as fix sent for 5.5

Changes from v1:
- Make tsens_features non-const to allow run time detection of features
- Pass tsens_sensor around as a const
- Fix a bug to release dev pointer in success path
- Address review comments from Bjorn and Stephen (thanks for the review)
- Add msm8998 and msm8996 DTSI changes for critical interrupts
