[PATCH 6.1.y 1/2] regulator: scmi: Simplify with scoped for each OF child loop

[Sasha Levin <sashal@kernel.org>]

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

[ Upstream commit 99cf5db9cdd39136fd5dbd10bda833aa0f870452 ]

Use scoped for_each_available_child_of_node_scoped() when iterating over
device nodes to make code a bit simpler.
