[PATCH v3 3/5] dt-bindings: media: arm,mali-c55: Add power domain

[Linus Walleij <linusw@kernel.org>]

Some Mali-C55 integrations place the ISP in a power domain. In
particular, RZ/V2H uses the CPG domain to manage its module clocks
through runtime PM.

Allow a single power domain and describe it in the example. Keep the
property optional for integrations that do not expose a power domain.
