Fix regression from "drm/amd/display: Fix MST BW calculation Regression"

Fix regression from "drm/amd/display: Fix MST BW calculation Regression"

[Mario Limonciello]

Hello,

The commit 338567d17627 ("drm/amd/display: Fix MST BW calculation 
Regression") caused a regression with some MST displays due to a mistake.

For 6.11.y here is the series of commits that fixes it:

commit 4599aef0c97b ("drm/amd/display: Fix Synaptics Cascaded Panamera 
DSC Determination")
commit ecc4038ec1de ("drm/amd/display: Add DSC Debug Log")
commit b2b4afb9cf07 ("drm/amdgpu/display: Fix a mistake in revert commit")

Can you please bring them back to 6.11.y?

Thanks!

Nor either of these :(

Gah; sorry I have a lot of remotes and didn't realize which one I was on 
when regressing this.  Here's the right hashes.

Determination")
