PM: Add initcall_debug style timing for suspend/resume
In order to diagnose overall suspend/resume times, we need basic instrumentation to break down the total time into per device timing, similar to initcall_debug. This patch adds the basic timing instrumentation, needed for a scritps/bootgraph.pl equivalent or humans. The bootgraph.pl program is still a work in progress, but is far enough along to know that this patch is sufficient. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Rafael J.
