Subject: [PATCH AUTOSEL 6.1 03/33] drm/amd/display: Correct DML calculation to align HW formula

From: Paul Hsieh <Paul.Hsieh@....com>

[ Upstream commit 26a9f53198c955b15161da48cdb51041a38d5325 ]

[Why]
In 2560x1440@...p eDP panel, some use cases will enable MPC
combine with RGB MPO then underflow happened. This case is
not allowed from HW formula. 

[How]
Correct eDP, DP and DP2 output bpp calculation to align HW
formula.
