there is no such thing as gen13. Please reword commit message to use
graphics version, although here it's probably more related to the
display engine (and hence DISPLAY_VER()). But then the code you are
adding here is probably dead code since 825477e77912 ("drm/i915/mtl:
Obtain SAGV values from MMIO instead of GT pcode mailbox")

If this is fixing anything what exactly is it? Otherwise it'd be more
"extend to next platforms" rather than "Fix".
