Subject: timer: permit statically-declared work with deferrable timers

Arjen, Thomas,

This patch is an enabler which hopefully can lead to simplification of code 
elsewhere. For example, it would turn Artem's patch I refer to in the commit
message (8eab945c5616fc984e97b922d6a2559be93f39a1) into just:

-static DECLARE_DELAYED_WORK(cache_cleaner, do_cache_clean);
+static DECLARE_DEFERRED_WORK(cache_cleaner, do_cache_clean);

rather than the creation of a __init helper that required touching 3 files.

I'm prepared to follow up with such simplifying patches if it's considered
worthwhile.

Cheers,
Phil
