dt-bindings: Drop more redundant 'maxItems/minItems' in if/then schemas

Another round from new cases in 5.19-rc of removing redundant
minItems/maxItems when 'items' list is specified. This time it is in
if/then schemas as the meta-schema was failing to check this case.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.
