I think the absence of both a DT binding and platforms that define the platform_data is a good indication that there are exactly zero users, I wouldn't worry about that unless you know of specific users. If it turns out that there are users on non-blackfin machines that still run on modern kernels, you should work with them to make a proper DT binding and drop the platform_data side of the driver.
