When CONFIG_OF_MDIO is set to be a module the code block is not
compiled. Use the IS_ENABLED macro that checks for both built in as
well as module.

Fixes tag needs some work:

  SHA1 should be at least 12 digits long
  Can be fixed by setting core.abbrev to 12 (or more) or (for git v2.11
  or later) just making sure it is not set (or set to "auto").
