x64, x2apic/intr-remap: basic apic ops support
Introduce basic apic operations which handle the apic programming. This
will be used later to introduce another specific operations for x2apic.
For the perfomance critial accesses like IPI's, EOI etc, we use the
native operations as they are already referenced by different
indirections like genapic, irq_chip etc.
64bit Paravirt ops can also define their apic operations accordingly.
