regulator: max77620: Use device_set_of_node_from_dev() 

commit 6f55c5dd1118b3076d11d9cb17f5c5f4bc3a1162 upstream.

The MAX77620 driver fails to re-probe on deferred probe because driver
core tries to claim resources that are already claimed by the PINCTRL
device. Use device_set_of_node_from_dev() helper which marks OF node as
reused, skipping erroneous execution of pinctrl_bind_pins() for the PMIC
device on the re-probe.
