[PATCH 5.4 241/434] drm: msm: a6xx: fix debug bus register configuration
From: Greg Kroah-Hartman

[ Upstream commit 7f4009c4bbea4438b50f3b12d1c57da3f5cd8db3 ]
Fix the cx debugbus related register configuration, to collect accurate
bus data during gpu snapshot. This helps with complete snapshot dump
and also complete proper GPU recovery.
