mlxsw: spectrum_router: Add support for double entry RIFs
In Spectrum-1, loopback router interfaces (RIFs) used for IP-in-IP encapsulation with an IPv6 underlay require two RIF entries and the RIF index must be even. Prepare for this change by extending the RIF parameters structure with a 'double_entry' field that indicates if the RIF being created requires two RIF entries or not. Only set it for RIFs representing ip6gre tunnels in Spectrum-1.
