drm/amd/display: reallocate DET for dual displays with high pixel rate ratio

Browse source

[Why]
For dual displays where pixel rate is much higher on one display,
we may get underflow when DET is evenly allocated.

[How]
Allocate less DET segments for the lower pixel rate display and
more DET segments for the higher pixel rate display
