[PATCH v3 2/6] dt-bindings: treewide: add feature-domains description in binding files

[Gatien Chevallier <gatien.chevallier@xxxxxxxxxxx>]

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.

Signed-off-by: Gatien Chevallier <gatien.chevallier@xxxxxxxxxxx>

Patch not present in V1 and V2.
