[net-next: PATCH v2 3/8] net: dsa: switch to device_/fwnode_ APIs

From: Marcin Wojtas
Date: Fri Jul 15 2022 - 04:51:14 EST

In order to support both ACPI and DT, modify the generic
DSA code to use device_/fwnode_ equivalent routines.
Drop using port's dn field and use only fwnode - update
all dependent drivers.
Because support for more generic fwnode is added,
replace '_of' suffix with '_fw' in related routines.
No functional change is introduced by this patch.
