x86 quirk: Fix polarity for IRQ0 pin2 override on SB800 systems
commit 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12 upstream.
On some SB800 systems polarity for IOAPIC pin2 is wrongly
specified as low active by BIOS. This caused system hangs after
resume from S3 when HPET was used in one-shot mode on such
systems because a timer interrupt was missed (HPET signal is
high active).
