Add architectural preparation for AVEC irqchip, including: 1. CPUCFG feature bits definition for AVEC; 2. Detection of AVEC irqchip in cpu_probe(); 3. New IPI type definition (IPI_CLEAR_VECTOR) for AVEC; 4. Provide arch_probe_nr_irqs() for large NR_IRQS; 5. Other related changes about the number of interrupts.
