Most of our helpers have relied on being selected so far through Kconfig, but that creates issues when we have multiple layers of helpers with some depending on others. Indeed, select doesn't select a dependency's dependencies, and thus isn't super intuitive. Depends on however doesn't have that limitation, so we can just switch all the drivers that were selecting DRM_DISPLAY_HDMI_HELPER to depend on it.
