The GIC chained handlers use do_IRQ() to call the subhandlers. This means that irq_enter() calls get nested, which leads to preempt count looking like we're in nested interrupts, which in turn leads to all system time being accounted as IRQ time in account_system_time(). Fix it by using generic_handle_irq(). Since these same functions are used in some systems (if cpu_has_veic) from a low-level vectored interrupt handler which does not go throught do_IRQ(), we need to do it conditionally.
