Subject: [PATCH] can: c_can: don't indicate triple sampling support for D_CAN

Patch-mainline: v4.14
References: bsc#1051510

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.
