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).

26 * Description:
27 *
28 * Public header file for the "GEnesis" common module "CSUM".
29 *
30 * "GEnesis" is an abbreviation of "Gigabit Ethernet Network System in Silicon"
31 * and is the code name of this SysKonnect project.
32 *
33 * Compilation Options:
34 *
35 * SK_USE_CSUM - Define if CSUM is to be used. Otherwise, CSUM will be an
36 * empty module.
37 *
38 * SKCS_OVERWRITE_PROTO - Define to overwrite the default protocol id
39 * definitions. In this case, all SKCS_PROTO_xxx definitions must be made
40 * external.
41 *
42 * SKCS_OVERWRITE_STATUS - Define to overwrite the default return status
43 * definitions. In this case, all SKCS_STATUS_xxx definitions must be made
44 * external.
45 *
46 * Include File Hierarchy:
47 *
48 * "h/skcsum.h"
49 * "h/sktypes.h"
50 * "h/skqueue.h"
