Ok, I guess these can be EXPORT_SYMBOL_GPL then, or you could remove them entirely by evaluating them in the boot loader and changing the device tree accordingly.
For device drivers, it's usually better to make decisions based on the revision of the device they talk to, not the revision of the entire SoC, since that requires knowledge of all SoCs that contain each version of the hardware macro.
