net: microchip: sparx5: Differentiate IPv4 and IPv6 traffic in keyset config

Browse Source 
This changes the port keyset configuration for Sparx5 IS2 so that

- IPv4 generates a IP4_TCP_UDP keyset for IPv4 TCP/UDP frames and a
  IP4_OTHER keyset for other IPv4 frames (both UC and MC)
- IPv6 generates a IP_7TUPLE keyset (both UC and MC)

ARP and non-IP traffic continues to generate the MAC_ETYPE keyset
