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).

114 * ============
115 *
116 * This routine clears the multicast tables and resets promiscuous mode.

119 *
120 *
121 * SK_INIT_IO
122 * ==========
123 *
124 * All permanent MAC addresses are read from EPROM.
125 * If the current MAC addresses are not already set in software,
126 * they are set to the values of the permanent addresses.
127 * The current addresses are written to the corresponding MAC.
