If there is another bridge after analogix_dp, then the connector object should not be created. This fixes following timeouts on Exynos5420-based Chromebook2 Peach-PIT board during boot: exynos-dp 145b0000.dp-controller: AUX CH cmd reply timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout!
