[PATCH] drm/msm: always parse interconnects

[PATCH] drm/msm: always parse interconnects

[Caleb Connolly]

The WARN_ON in dpu_runtime_resume() fires constantly on non-SC7180
platforms. As SDM845 now has interconnects hooked up we should always
try and parse them.

Fixes: 627dc55c273d ("drm/msm/disp/dpu1: icc path needs to be set before dpu runtime resume")

I believe this series in msm-next already solves this
