[PATCH] drm/amd/display: refactor CalculateWriteBackDelay to use vba_vars_st ptr

From: Tom Rix
Date: Sat Sep 17 2022 - 14:38:43 EST


Mimimize the function signature by passing a pointer and an index instead
of passing several elements of the pointer.

The dml2x,dml3x families uses the same algorithm. Remove the duplicates.
Use dml20_ and dml30_ prefix to distinguish the two variants.
