net: ti: icssg-prueth: Set XDP feature flags for ndev

xdp_features demonstrates what all XDP capabilities are supported
on a given network device. The driver needs to set these xdp_features
flag to let the network stack know what XDP features a given driver
is supporting. These flags need to be set for a given ndev irrespective
of any XDP program being loaded or not.
