[PATCH] regulator: bq257xx: drop confusing configuration of_node

[Johan Hovold <johan@kernel.org>]

The driver reuses the OF node of the parent multi-function device but
still sets the of_node field of the regulator configuration to any prior
OF node.

Since the MFD child device does not have an OF node set until probe is
called, this field is set to NULL on first probe and to the reused OF
node if the driver is later rebound.

As the device_set_of_node_from_dev() helper drops a reference to any
prior OF node before taking a reference to the new one this can
apparently also confuse LLMs like Sashiko which flags it as a potential
use-after-free (which it is not).

Drop the confusing and redundant configuration of_node assignment.

This is a follow-up to the reused OF node imbalance series:

to address a false-positive Sashiko report.
