drm/rockchip: rk3066_hdmi: Add missing Kconfig selects

Browse Source 
rk3066_hdmi.c calls drm_bridge_connector_init(), but
ROCKCHIP_RK3066_HDMI selects neither DRM_BRIDGE_CONNECTOR nor
DRM_DISPLAY_HELPER, whose module carries the bridge-connector code. A
configuration with ROCKCHIP_RK3066_HDMI as the only enabled Rockchip
output option fails to link:

  aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/rk3066_hdmi.o: in function `rk3066_hdmi_bind':
  rk3066_hdmi.c:(.text+0x7a4): undefined reference to `drm_bridge_connector_init'
  aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/rk3066_hdmi.o: in function `rk3066_hdmi_bridge_atomic_enable':
  rk3066_hdmi.c:(.text+0xe74): undefined reference to `drm_atomic_helper_connector_hdmi_update_infoframes'

Select both, like ROCKCHIP_CDN_DP, ROCKCHIP_LVDS and ROCKCHIP_RGB do.
DRM_BRIDGE_CONNECTOR in turn selects DRM_DISPLAY_HDMI_STATE_HELPER,
which resolves the second symbol.
