apic: add global apic_get_class()

Browse source 
Every configuration has only up to one APIC class and we'll be extending
the class with a function that can be called without an instanced
object, so a direct access to the class is convenient.

This patch will break compilation if some code uses apic_get_class()
with CONFIG_USER_ONLY.
