drivers: psci: annotate timer on stack to silence odebug messages

When DEBUG_OBJECTS config is enabled, we get the below odebug warnings:

ODEBUG: object is on stack, but not annotated

WARNING: CPU: 3 PID: 1304 at kernel/lib/debugobjects.c:300 __debug_object_init+0x1f0/0x458

This patch annotates the timer on the stack using setup_timer_on_stack
function to remove the above warnings.
