[PATCH] regulator: as3722: use the platform OF node setter

[Yige Jiang <yigejiang86@gmail.com>]

as3722_get_regulator_dt_data() gets the regulators child node and
assigns it only to dev.of_node. Platform device release now puts
dev.fwnode, leaving the acquired node reference unreleased.

Use platform_device_set_of_node() to synchronize both fields and
give the device its own reference, then put the local lookup
reference. This keeps the node valid for regulator matching and
the platform device lifetime, while also replacing the previous
device-owned reference on a probe retry.
