Make DEBUG take precedence over DYNAMIC_PRINTK_DEBUG

Statically defined DEBUG should take precedence over
dynamically enabled debugging; otherwise adding DEBUG
(like, for example, via CONFIG_DEBUG_KOBJECT) does not
have the expected result of printing pr_debug() and dev_dbg()
messages unconditionally.
