[PATCH] dt-bindings: Drop redundant maxItems/items

[Rob Herring <robh@kernel.org>]

'maxItems' equal to the 'items' list length is redundant. 'maxItems' is
preferred for a single entry while greater than 1 should have an 'items'
list.

A meta-schema check for this is pending once these existing cases are
fixed.
