Add "power-domains" property in stm32 serial binding to avoid:

serial@40010000: Unevaluated properties are not allowed
('power-domains' were unexpected)

It would be better if you checked whether it can be part of power domain
or not. What if the DTS is wrong?

Hi Krzysztof,

I'm not sure to understand, but if you mean that there is no
power-domains properties right now in all stm32mp device trees
and so it does not required to add this stm32 serial bindings:

Theses will be upstreamed in the future, and because power-domains
property is optional, I can add it right now in stm32 serial binding
to anticipate.

Best regards,
Valentin

No. You used argument: "add because DTS has it" and I want different
argument: "add because it is the right thing to do because foo and bar".
If DTS is wrong, then your commit and this explanation is wrong.
