Subject: [PATCH V3 09/11] ARM: samsung: register syscore_ops for timer resume directly

From: Stephen Warren <swarren@...dia.com>

Instead of using struct sys_timer's resume function, register syscore_ops
directly in s3c2410_timer_init(). This will allow the sys_timer suspend/
resume fields to be removed, and eventually lead to a complete removal of
struct sys_timer.
