3.16.52-rc1 review patch. If anyone has any objections, please let me know.

commit fb5f0b3ef69b95e665e4bbe8a3de7201f09f1071 upstream.
The D_CAN controller doesn't provide a triple sampling mode, so don't set the CAN_CTRLMODE_3_SAMPLES flag in ctrlmode_supported. Currently enabling triple sampling is a no-op.
