The recently added PTN3460 device driver uses interfaces that
are provided by the KMS helper infrastructure, so we should
explicitly select that to avoid this linker error:
ERROR: "drm_helper_probe_single_connector_modes"
[drivers/gpu/drm/bridge/ptn3460.ko] undefined!
ERROR: "drm_helper_connector_dpms" [drivers/gpu/drm/bridge/ptn3460.ko]
undefined!
We have to drop the I2C dependency to avoid a circular dependency
chain, but that's ok because DRM already selects I2C.

I found this today doing randconfig builds on linux-next.
