Subject: [PATCH v2] dt-bindings: watchdog: improve QCOM compatible parsing for modern chips

Parse compatible as expected for modern QCOMs.

Fixes warnings as:

It seems this patch received three reviews but was not picked up. David,
do you plan to work on this?

These do not look correct without appropriate fallback.

Yes the situation there isn't optimal and I'm afraid I cannot solve it
in scope of this change.

Previously I was thinking about also merging MSM timer into this
binding, which shares the compatible, but uses different driver. Sadly,
currently don't have a time for it (have some WIP patch locally, if
anyone interested to take a look).

I'm (re-)sending v3 with another S-off, but it solves only warnings
described in commit message.
