feature-domains is an optional property that allows a peripheral to
refer to one or more feature domain controller(s).

Description of this property is added to all peripheral binding files of
the peripheral under the STM32 System Bus. It allows an accurate
representation of the hardware, where various peripherals are connected
to this firewall bus. The firewall can then check the peripheral accesses
before allowing it to probe.

Not how common properties work. Consumer properties should be in a 
schema with 'select: true' (the one you are referencing) and here you 
just need to define the entries. Like clocks, power-domains, etc.

> +    minItems: 1

Why is this variable and what is each entry?

I still don't like the naming. Everything is a feature and a domain... 

It might be a bit easier to come up with a name with multiple users of 
this binding presented. I'm hesistant to define any new common binding 
with only 1 user as I've said multiple times on this binding.
