drm/panel: r66451: select CONFIG_DRM_DISPLAY_DP_HELPER

The newly added driver only builds when DRM_DISPLAY_DP_HELPER is enabled:

x86_64-linux-ld: drivers/gpu/drm/panel/panel-visionox-r66451.o: in function `visionox_r66451_enable':
panel-visionox-r66451.c:(.text+0x105): undefined reference to `drm_dsc_pps_payload_pack'

Select both CONFIG_DRM_DISPLAY_DP_HELPER and CONFIG_DRM_DISPLAY_HELPER to
ensure the helper function is always available.
