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

[Manivannan Sadhasivam]

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")
