net: ti: icssg: Add ICSSG ethernet driver
This is the PRUSS Ethernet driver for TI AM654 SR2.0 and later SoCs 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.
