[PATCH] regulator: core: Fix resolve supply

[Kory Maincent <kory.maincent@bootlin.com>]

The regulator should not use the device parent to resolve the regulator
supply. It fails to resolve the correct supply when the of_node
variable in the regulator_config structure is not within the parent
node.

Fixes: 6261b06de565 ("regulator: Defer lookup of supply to regulator_get")

It is weird that it wasn't seen before, maybe there was not any case
were it can't find the supply_name from the parent device.
