Subject: drm/amdgpu: Init GFX10_ADDR_CONFIG for VCN v3 in DPG mode.

From: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl>

commit 8bf073ca9235fe38d7b74a0b4e779cfa7cc70fc9 upstream.

Otherwise tiling modes that require the values form this field
(In particular _*_X) would be corrupted upon video decode.

Copied from the VCN v2 code.

Fixes: 99541f392b4d ("drm/amdgpu: add mc resume DPG mode for VCN3.0")
