drm/xe: Make display part of Wa_22019338487 a device workaround

Browse Source 
The display part of Wa_22019338487 (i.e., avoiding use of stolen memory)
is using a platform test rather than an graphics/media IP test.  Since
this workaround is focused on non-GT uses of stolen memory, it makes
sense that we'd want to still apply the workaround on affected platforms
even if the GTs themselves are disabled via configfs.
