Subject: [PATCH] lib: Make SECTION_MISMATCH_WARN_ONLY depend on DEBUG_SECTION_MISMATCH

CONFIG_SECTION_MISMATCH_WARN_ONLY says to turn the errors enabled by
CONFIG_DEBUG_SECTION_MISMATCH into warnings. As such there's no need
to set the former if the latter is not enabled.

Currently there's no connection between the two, meaning we can end up
with this slightly confusing situation:

  # CONFIG_DEBUG_SECTION_MISMATCH is not set
  CONFIG_SECTION_MISMATCH_WARN_ONLY=y

So make CONFIG_SECTION_MISMATCH_WARN_ONLY depend on
CONFIG_DEBUG_SECTION_MISMATCH.
