Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helpercode should always be selected by the driver that needs it, for theconvenience of the final user configuring a kernel.The user who configures a kernel should not need to know which helpersare needed for the driver he is interested in.
