drm/display: stop depending on DRM_DISPLAY_HELPER
Kconfig symbols should not declare dependency on DRM_DISPLAY_HELPER.
Move all parts of DRM_DISPLAY_HELPER to an if DRM_DISPLAY_HELPER block.
It is not possible to make those symbols select DRM_DISPLAY_HELPER
because of the link issues when a part of the helper is selected to be
built-in, while other part is selected to be as module. In such a case
the modular part doesn't get built at all, leading to undefined symbols.
The only viable alternative is to split drm_display_helper.ko into
several small modules, each of them having their own dependencies.
