net: ti: am65-cpsw-nuss: Define bind method for CPSW driver

Browse Source 
CPSW driver is defined as UCLASS_MISC driver which needs to be probed
explicitly. Define bind method for CPSW driver to scan and bind
ethernet-ports with UCLASS_ETH driver which will eventually probe CPSW
driver and avoid probing CPSW driver explicitly.
