Subject: [PATCH v1 1/2] dt-bindings: qspi: cdns,qspi-nor: constrain minItems/maxItems of resets

The QSPI controller needs three reset items to work properly on JH7110 SoC,
so there is need to change the maxItems's value to 3 and add minItems
whose value is equal to 2. Other platforms do not have this constraint.
