scsi: dt-bindings: ufs: qcom: Fix ICE phandle

The check for 'qcom,ice' property is wrong. Fix it by checking using
if-required clause and expand the clocks minItems and maxItems for
platforms where 'qcom,ice' is not required so that it includes platforms
with single reg entry and clocks that do not provide an ICE one.
