My attempt to further cleanup pic/ioapic checks using irqchip_mode + other cleanups in that area. The goal is to only check against irqchip_mode and not to rely on vpic/vioapic variables anymore to test for existence of pic/ioapic. This will avoid any possible races when creating the kernel irqchip fails. Feel free to nack if a a certain cleanup is not worth it.
