x86: SB600: skip ACPI IRQ0 override if it is not routed to INT2 of IOAPIC
commit 26adcfbf00e0726b4469070aa2f530dcf963f484 upstream.
On some more HP laptops BIOS reports an IRQ0 override
but the SB600 chipset is configured such that timer
interrupts go to INT0 of IOAPIC.
Check IRQ0 routing and if it is routed to INT0 of IOAPIC skip the
timer override.
