mlxsw: reg: Add support for ritr_loopback_ipip6_pack()

Browse Source 
The RITR register is used to configure the router interface table.

For IP-in-IP, it stores the underlay source IP address for encapsulation
and also the ingress RIF for the underlay lookup.

Add support for IPv6 IP-in-IP configuration.
