If DRM_ITE_IT6505 is y but DRM_DP_HELPER is m, building failed:

drivers/gpu/drm/bridge/ite-it6505.o: In function `it6505_i2c_remove':
ite-it6505.c:(.text+0x35c): undefined reference to `drm_dp_aux_unregister'
drivers/gpu/drm/bridge/ite-it6505.o: In function `it6505_dpcd_read':

drivers/gpu/drm/bridge/ite-it6505.o: In function `it6505_get_dpcd':
ite-it6505.c:(.text+0x4a4): undefined reference to `drm_dp_dpcd_read'
drivers/gpu/drm/bridge/ite-it6505.o: In function `it6505_dpcd_write':
ite-it6505.c:(.text+0x52c): undefined reference to `drm_dp_dpcd_write'

Select DRM_DP_HELPER for DRM_ITE_IT6505 to fix this.
