[PATCH] net: ti: am65-cpsw-nuss: Ignore disabled ethernet ports

[Siddharth Vadapalli]

Currently, the bind callback of the driver namely am65_cpsw_nuss_bind()
registers all ethernet ports including the ones that have been disabled
in the device-tree. Since the ports that have been disabled are ought to
be ignored, fix the implementation to register only the enabled ports as
indicated by their 'status' in their respective device-tree node.
