x86/platform: Introduce APIC post-initialization callback

Browse source

Some subarchitectures (such as vSMP) need to slightly adjust the
underlying APIC structure. Add an APIC post-initialization callback
to 'struct x86_platform_ops' for this purpose and use it for
adjusting the APIC structure on vSMP systems.
