arm/{pxa,sa1100,nomadik}: Don't disable irqs in set_next_event and set_mode
These functions are called with irqs already off. This commit removes the calls to raw_local_irq_save and raw_local_irq_restore on platforms that don't have to use a shared interrupt for their timekeeping. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
