net: atlantic: decouple aq_set_data_fl3l4() from driver internals

Refactor aq_set_data_fl3l4() to take an ethtool_rx_flow_spec pointer and
an explicit HW register location instead of driver-internal structures
(aq_nic_s, aq_rx_filter). This makes the function reusable for PTP
filter setup which constructs flow specs independently.

Key changes:
- Add aq_is_ipv6_flow_type() helper to derive IPv6 status from the
  flow_type field, replacing the dependency on rx_fltrs->fl3l4.is_ipv6
  shared state.
- Change aq_set_data_fl3l4() signature to accept (fsp, data, location,
  add) and export it via aq_filters.h.
- Update aq_add_del_fl3l4() to compute the HW register location and
  pass it explicitly.
