[PATCH v5 2/5] drm/dp: fix link probing for devices supporting DP 1.4+

From: Quentin Schulz DP 1.4 introduced a DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT bit in DP_TRAINING_AUX_RD_INTERVAL register. If set, DPCD registers from DP_DPCD_REV to DP_ADAPTER_CAP should be retrieved starting from DP_DPCD_REV_EXTENDED. All registers are copied except DP_DPCD_REV, DP_MAX_LINK_R
