drm/bridge: analogix_dp: Don't create useless connectors

Browse source 
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!
