Subject: [PATCH 4/4] x86_64 ioapic: Improve the heuristics for when

For some CK804 boards, BIOS forget set to 8254 timer to apic0/pin2, and
still leave it at apic0/pin0. but mptable and acpi said 8254 timer is to
apic0/pin2. At such case we should try apic0/pin0 with INT mode instead
of ExtINT mode.
