[RFC v2 PATCH 13/21] x86/apic: IRQ vector remapping on slave for slave CPUs

Add a facility to use IRQ vector different from online CPUs on slave CPUs. When alternative vector for IRQ is registered by remap_slave_vector_irq() and the IRQ affinity is set only to slave CPUs, the device is configured to use the alternative vector. Current patch only supports MSI and Intel
