The IOAPIC specification defined EOI register for 0x20 version. The original vioapic code implemented this register but the version was still export as 0x11. Tried to set 0x20, the Linux kernel has't access this EOI register, still rely on lapic to send eoi. From Linux ioapic driver comments, it says that only send EOI via EOI register when met IOAPIC hardware bug. This patch removes all 0x20 IOAPIC code to reduce the code size.
