[PATCH] sk98lin: fix workaround for yukon-lite chipset (> rev 7) 

Yukon-Lite chipset needs workaround for revision 7 (or later).
Without this patch, chip gets stuck in low power mode and never
boots. Newer SysKonnect vendor code already had same patch.

Related bug in skge is http://bugs.gentoo.org/87822



Chris, please add for 2.6.12.2
