drm/msm/dpu: Fix Kaanapali CWB register configuration
The Kaanapali DPU catalog defines kaanapali_cwb[] with the correct
CWB base addresses for this platform (0x169200, 0x169600, 0x16a200,
0x16a600), but the dpu_kaanapali_cfg struct was mistakenly pointing
to sm8650_cwb instead. The SM8650 CWB blocks sit at completely
different offsets (0x66200, 0x66600, 0x7E200, 0x7E600), so using
them on Kaanapali would program CWB registers at wrong addresses,
corrupting unrelated hardware blocks and breaking writeback capture.
Fix this by pointing .cwb to the correct kaanapali_cwb array.
