Subject: [PATCH] dt-bindings: iio: addac: adi,74115: Add missing maxItems

Running 'make dt_binding_check' gives following warnings:
iio/addac/adi,ad74115.example.dtb:
addac@0: adi,conv2-range-microvolt: 'oneOf' conditional failed, one must
be fixed:
        4282967296 is not one of [-2500000, 0]
        4282967296 is not one of [-12000000, 0]
        -2500000 was expected
        -104000 was expected
        625000 was expected

addac@0: Unevaluated properties are not allowed
('adi,conv2-range-microvolt' was unexpected)
        From schema: iio/addac/adi,ad74115.yaml

As every property with standard suffix has inferred type of array of
cells, adi,conv2-range-microvolt is required by meta-schemas/cell.yaml
to have maxItems >= 2. Fix these errors by setting maxItems to 2.
