Please put the node alphabetically, so before &dp.

Also this patch should be squashed with previous one (regulators),
because adding non-controllable fixed regulators on its own does not
bring benefits. Linux will not disable them. You added these
regulators for the bridge below. Without the bridge, their existence
does not have much sense.

Best regards,
Krzysztof
