[openEuler-5.10 203/303] drm/amd/display: fix incorrect CM/TF programming sequence in dwb

From: Roy Chan roy.chan@amd.com

stable inclusion from stable-5.10.67 commit 63ebc1f1df813ebb40d19449c356480555008166 bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...

--------------------------------

[ Upstream commit 781e1e23131cce56fb557e6ec2260480a6bd08cc ]

[How] the programming sequeune was for old asic. the correct programming sequeunce should be similar to the one used in mpc. the fix is copied from the mpc programming sequeunce.
