ARM: sa1100: convert timer suspend/resume to clock_event_device
Move sa1100's timer suspend/resume functions from struct sys_timer sa1100_timer into struct clock_event_device ckevt_sa1100_osmr0. This will allow the sys_timer suspend/resume fields to be removed, and eventually lead to a complete removal of struct sys_timer. Signed-off-by: Stephen Warren <swarren@nvidia.com>
