[PATCH 4/7] dt-bindings: power: Extend nodename pattern for power-domain providers

[Ulf Hansson <ulf.hansson@linaro.org>]

The existing binding requires the nodename to have a '@', which is a bit
limiting for the wider use case. Therefore, let's extend the pattern to
allow either '@' or '-'.

Additionally, let's update one of the examples to show how the updated
pattern could be used.

Fixes: a3f048b5424e ("dt: psci: Update DT bindings to support hierarchical PSCI states")
