Subject: [PATCHv2 3/7] x86: make apic_disable() static and init

apic_disable() is only used in apic.c, so it does not
need the prototype which was introduced in
commit 08306ce61d6848e6fbf74fa4cc693c3fb29e943f .
Therefore we remove it from the header and make it static.

It is also called only from init code, so we mark it as such.
