We have established previously we stop using relocations starting
from gen12 platforms with Tigerlake as an exception. Unfortunately
we need extend transition period and support relocations for two
other igfx platforms - Rocketlake and Alderlake.
As Alderlake is coming in two variants - S and P and only S landed
upstream already we will need to extend the relocation enabling
condition one more time for P version in the future.
