[ Upstream commit d7e3fd658248f257006227285095d190e70ee73a ]

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.

69a9dcbd ("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().
