This series adds more input validation to Kconfig, specifically checking
that ranges for numeric options are properly ordered. This check was
originally introduced as part of kconfirm [1], but there are no findings
for this across the tree, so the check can be added directly into Kconfig.

Patch 1/2 adds a prop_err() function to match the existing prop_warn(),
which is then used in patch 2/2 where the check is introduced.
