Yu Wang 1e1886794e hv: vioapic: remove EOI register support
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.
