mlxsw: spectrum_router: Implement common RIF core
The mlxsw driver currently implements three types of RIFs. VLAN and FID RIFs for L3 interfaces on top of VLAN-aware and VLAN-unaware bridges (respectively) and Subport RIFs for all other L3 interfaces. All the RIF types follow a common configuration procedure, which only differs in the type-specific bits. The patch exploits this fact and consolidates the common code paths, thereby simplifying the code and making it more extensible. This work also prepares the driver for use with future ASICs, where the range of the Subport RIFs will be extended and their configuration modified accordingly. By merely implementing a new RIF operations and selecting it during initialization, the same driver could be re-used.
