A HAS_DMC_WAKELOCK() macro gives more semantic than openly checking the
display version. Define it and use it where appropriate.

v2:
  - Make this patch contain only the non-functional refactor. Functional
    changes related to including HAS_DMC() in the macro are done in
    upcoming changes. (Jani)
