[PATCH 07/22] dynamic_debug: consolidate DEFINE_DYNAMIC_DEBUG_METADATA definitions

[Rasmus Villemoes <linux@rasmusvillemoes.dk>]

Instead of defining DEFINE_DYNAMIC_DEBUG_METADATA in terms of a helper
DEFINE_DYNAMIC_DEBUG_METADATA_KEY, that needs another helper
dd_key_init to be properly defined, just make the various #ifdef
branches define a _DPRINTK_KEY_INIT that can be used directly, similar
to _DPRINTK_FLAGS_DEFAULT.
