Instead of making all these changes in this patch, isn't it cleaner to
include the platform check for DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE in
invalid_flag() itself?

Also is it just LNL and BMG, or other future platforms too? In that case
instead of using IS_LUNARLAKE() kind of macros, use intel_graphics_ver()
checks, so we don't need to keep adding a new patch/check for each
platform.
