sk98lin: remove obsolete driver
All the hardware supported by this driver is now supported by the skge driver. The last remaining issue was support for ancient dual port SysKonnect fiber boards, and the skge driver now does these correctly (p.s. sk98lin was always broken on these old dual port boards anyway).
