MLK-17275-2: drm/bridge: it6263: Add support for OF_DYNAMIC

commit 3b487277f318e60f7f3fbb52061221ab6a53b398 from
https://github.com/nxp-imx/linux-imx



When CONFIG_OF_DYNAMIC is used, and this driver is enabled in
devicetree, but fails to probe a physical i2c client, it should disable
it's remote endpoint, so that the DRM master device won't fail to bind
the other available devices.
Usually, the remote endpoint of this device is a DRM encoder. If a DRM
encoder fails to bind, the DRM master device will also fail to bind.
This is why, we should disable the encoder node dynamically in
devicetree.
