This is the PRUSS Ethernet driver for TI AM654 Sr2.0 and laterSoCs with

the ICSSG PRU Sub-system running EMAC firmware. ICSSG Subsystem supports two slices per instance. This driver caters to both slices / ports of the icssg subsystem.
Since it is not possible for Ethernet driver to register more than one port for a given instance, this patch introduces top level PRUETH as UCLASS_MISC and binds UCLASS_ETH to individual ports in order to support bringing up more than one Ethernet interface in U-Boot.
Since top level driver is UCLASS_MISC, board files would need to instantiate the driver explicitly.
