Subject: [PATCH] clocksource/drivers/jcore: Use request_percpu_irq()

Use request_percpu_irq() instead of request_irq() to solve
the following sparse warning:

jcore-pit.c:173:40: warning: incorrect type in argument 5 (different address spaces)
jcore-pit.c:173:40:    expected void *dev
jcore-pit.c:173:40:    got struct jcore_pit [noderef] __percpu *static [assigned] [toplevel] jcore_pit_percpu

Compile tested only.
