soc: qcom: ice: Fix the error code when 'qcom,ice' property is not found

When both 'ice' reg entry and 'qcom,ice' property are not found in DT, then
it implies that ICE is not supported. So return -EOPNOTSUPP instead of
-ENODEV to client drivers to specify ICE functionality is not supported.

Fixes: b9ab7217dd7d ("soc: qcom: ice: Return proper error codes from devm_of_qcom_ice_get() instead of NULL")
