ARM: qcom: scm: Add logging of actual return code from scm call
When an error occurs during an scm call the error returned is remapped so we lose the original error code. This means that when an error occurs we have no idea what actually failed within the secure environment. Add a logging statement that will log the actual error code from scm call allowing us to easily determine what caused the error to occur.
