This causes build failures if we want the camera driver to be built-in. This can be solved by turning the option into "tristate", which unfortunately causes another problem, because the driver incorrectly calls a platform-internal interface for omap4_ctrl_pad_readl/omap4_ctrl_pad_writel. To work around that, we can export those symbols, but that isn't really the correct solution, as we should not have dependencies on platform code this way.
