[PATCH 2/4] kvm: x86: allow set apic and ioapic debug dynamically

[Yi Wang <wang.yi59@zte.com.cn>]

There are two *_debug() macros in kvm apic source file:
- ioapic_debug, which is disable using #if 0
- apic_debug, which is commented

Maybe it's better to control these two macros using CONFIG_KVM_DEBUG,
which can be set in make menuconfig.
