Enable cdn_dp and create a cdn-dp-sound for the DP audio. Delete the
endpoints between dp and vopL for gru, since we want the DP only use
VOP big, which can support 4K mode.

applied for 4.17 after dropping the vop-related hacks

The devicetree should only describe the hardware and is generally not meant
to do configuration-related things. Selecting the most suitable vops for any
given combination of outputs should be in the realm of the driver and not
hard-coded in the dt.
