net: ti: am65-cpsw: Update hw timestamping filter for PTPv1 RX packets

Browse Source 
CPTS module of CPSW supports hardware timestamping of PTPv1 packets.Update
the "hwtstamp_rx_filters" of CPSW driver to enable timestamping of received
PTPv1 packets. Also update the advertised capability to include PTPv1.
