drm/rockchip: dw_dp: Select DRM_BRIDGE_CONNECTOR

Browse Source 
dw_dp-rockchip.c calls drm_bridge_connector_init(), but ROCKCHIP_DW_DP
does not select DRM_BRIDGE_CONNECTOR. A configuration with
ROCKCHIP_DW_DP as the only enabled Rockchip output option fails to
link:

  aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/dw_dp-rockchip.o: in function `dw_dp_rockchip_bind':
  dw_dp-rockchip.c:(.text+0x1d4): undefined reference to `drm_bridge_connector_init'

Five other Rockchip encoder options that call
drm_bridge_connector_init() (ROCKCHIP_ANALOGIX_DP, ROCKCHIP_CDN_DP,
ROCKCHIP_DW_HDMI_QP, ROCKCHIP_LVDS, ROCKCHIP_RGB) already select it,
which masks the gap in any configuration that enables one of them.
ROCKCHIP_INNO_HDMI is covered through its DRM_INNO_HDMI core option.

The same change was posted by Marius Dinu in March and dropped when
the failure stopped reproducing in his build. The failure is
configuration-dependent - any other enabled option that selects
DRM_BRIDGE_CONNECTOR hides it - and it still reproduces on current
drm-misc-next with the configuration described above.

Select DRM_BRIDGE_CONNECTOR like the other users do.
