[v5,0/8] Convert DA906{1,2} bindings to json-schema

Convert the below bindings to json-schema
1) DA906{1,2} mfd bindings
2) DA906{1,2,3} onkey bindings
3) DA906{1,2,3} thermal bindings

Also add fallback for DA9061 watchdog device and document
DA9063 watchdog device.

Document missing gpio child node for da9062 and update MAINTAINERS entries.

Merge strategy:
Since there is binding dependency between input, thermal, watchdog and MFD
subsystem. it is decided that this series will go through the MFD tree.
So once the respective subsystem maintainers, DT and Renesas are happy
with the patch they can give an ack/rb tag, so that it can be applied to
MFD tree.

Note:

This patch series is same as v3.1 as it allows the tools (PW, b4)
to compare against previous versions.

The review comments/tags received for v4 + (a.k.a v3.1) will be
addressed in the next version(v5).
