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 v5.6-rc2.

Changes since v6:
 - Fix up some lines over 80 characters
 - Remove Link tags

Changes since v5:¬
 - Introduce a function tsens_register_irq to handle uplow and critical
   interrupt registration and reduce code duplication
 - Clarify reason for patch 04

Changes from v4:
- Add back patch 1 from v3[*], I mistakenly didn't post it for v4.
- Remove spinlock from critical interrupt handling
- Change critical interrupt handler to fall thru watchdog bark handling to
  handle critical interrupts too

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
