From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>
commit 8d35217149daa33358c284aca6a56d5ab92cfc6c upstream.
Lower the requested CFG bus bandwidth for the SDM670 platform. The
default value is 153600 kBps, which is twice as big as required by the
platform according to the vendor kernel.
Fixes: a55c8ff252d3 ("drm/msm/mdss: Handle the reg bus ICC path")
