Subject: [PATCH AUTOSEL 6.12 206/486] net: ethernet: ti: cpsw_new: populate netdev of_node

From: Alexander Sverdlin <alexander.sverdlin@...mens.com>

[ Upstream commit 7ff1c88fc89688c27f773ba956f65f0c11367269 ]

So that of_find_net_device_by_node() can find CPSW ports and other DSA
switches can be stacked downstream. Tested in conjunction with KSZ8873.
