dt-bindings: i2c: qcom,i2c-cci: add missing clocks constraint in if:then:

Top level defines clocks as variable from 3 to 6 items, so each clause
in if:then: should narrow it further with explicit min and maxItems.
Without minItems, the constrain from top-level is being applied, thus
qcom,msm8996-cci allows between 3 and 4 clocks.
