x86, quirk: Fix SB600 revision check
Commit 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12 (x86 quirk: Fix polarity for IRQ0 pin2 override on SB800 systems) introduced a regression. It removed some SB600 specific code to determine the revision ID without adapting a corresponding revision ID check for SB600. See this mail thread: http://marc.info/?l=linux-kernel&m=129980296006380&w=2 This patch adapts the corresponding check to cover all SB600 revisions.
