net: Introduce DSA class for Ethernet switches
DSA stands for Distributed Switch Architecture and it covers switches that
are connected to the CPU through an Ethernet link and generally use frame
tags to pass information about the source/destination ports to/from CPU.
Front panel ports are presented as regular ethernet devices in U-Boot and
they are expected to support the typical networking commands.
DSA switches may be cascaded, DSA class code does not currently support
this.

+ Enable driver model for DSA switches
+
+ Adds UCLASS_DSA class supporting switches that follow the Distributed
+ Switch Architecture (DSA). These switches rely on the presence of a
+ management switch port connected to an Ethernet controller capable of
+ receiving frames from the switch. This host Ethernet controller is
+ called the "master" Ethernet interface in DSA terminology.
+ This is currently implemented in net/dsa-uclass.c, refer to
+ include/net/dsa.h for API details.
