net: ethernet: ti: am65-cpsw: avoid devm_alloc_etherdev, fix module removal

Browse source

Usage of devm_alloc_etherdev_mqs() conflicts with
am65_cpsw_nuss_cleanup_ndev() as the same struct net_device instances
get unregistered twice. Switch to alloc_etherdev_mqs() and make sure
am65_cpsw_nuss_cleanup_ndev() unregisters and frees those net_device
instances properly.

With this, it is finally possible to rmmod the driver without oopsing
the kernel.
