[PATCH] drm/rockchip: rgb: make connector a pointer in struct rockchip_rgb

[Alex Bee <knaerzche@gmail.com>]

As reported at [1] Coverity complains about an used value.

Let's make drm_connector a pointer in struct rockchip_rgb and "remove
redundant assignment of pointer connector".

Fixes: 2e87bf389e13 ("drm/rockchip: add DRM_BRIDGE_ATTACH_NO_CONNECTOR flag to drm_bridge_attach")
Addresses-Coverity: ("Unused value")
