drm/i915/display: Use IP version check for Wa_14020863754

Wa_14020863754 applies to the display IP, so we should be checking on
display IP version instead of platform. So, let's replace
display->platform.battlemage with the proper IP version check (14.01 for
Xe2_HPD).

Furthermore, for workarounds, we should be checking on full IP versions
to avoid applying the workaround to some variant of the IP that could
theoretically appear in the future (which is likely to have a different
minor release number), since the issue addressed by the workaround could
be fixed in such new release.
