irqchip/jcore-aic, clocksource/drivers/jcore: Fix jcore-pit interrupt request
The jcore-aic irqchip does not have separate interrupt numbers reserved for cpu-local vs global interrupts. Therefore the device drivers need to request the given interrupt as per CPU interrupt. 69a9dcbd2d65 ("clocksource/drivers/jcore: Use request_percpu_irq()") converted the clocksource driver over to request_percpu_irq(), but failed to do add all the required changes, resulting in a failure to register PIT interrupts. Fix this by: 1) Explicitly mark the interrupt via irq_set_percpu_devid() in jcore_pit_init(). 2) Enable and disable the per CPU interrupt in the CPU hotplug callbacks. 3) Pass the correct per-cpu cookie to the irq handler by using handle_percpu_devid_irq() instead of handle_percpu_irq() in handle_jcore_irq().
