ethernet: ti: am65-cpsw: allow hwts for ptp sync msgs and others

Since am65-cpsw supports rx hardware timestamps for any packet
(HWTSTAMP_FILTER_ALL), allow hardware timestamp at least for existent
rx filters. Despite of this, hw supports only two filter modes:
HWTSTAMP_FILTER_NONE and HWTSTAMP_FILTER_ALL that is still shown with
"ethtool -T inf_name".
