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.

Older dtschema behaved differently and missing minItems was implied in
if:then:. However the preferred policy is to be explicit about such
schema - define strict constraints in if:then:.
