Alderlake-S is a Gen 12 based hybrid processor architeture. As it
belongs to Gen 12 family, it uses the same GTT stolen memory settings
like its predecessors - ICL(Gen 11) and TGL(Gen 12). This patch inherits
the gen11 and gen 9 quirks for determining base and size of stolen
memory.

Note that this patch depends on commit 0883d63b19bb
("drm/i915/adl_s: Add ADL-S platform info and PCI ids")
