Here is the SWDT handling series for R-Car Gen4: it adds the SWDT node to the
SoC DTSI and then marks it as "reserved" in the board DTs.

No bindings update is needed here. My previous comment about some Gen4
having no bit for reset was wrong. I found them in the docs meanwhile.
This only leaves V3H as an exception. I will add it on top of my WDT
binding doc refactoring series later.

A minor irregularity is that the RWDT was not enabled for V4H White-Hawk
yet. This is fixed here as well. Of course, this series passes
'dtbs_check'.

Thanks and happy hacking!
