./drivers/gpu/drm/i915/display/intel_fbdev.h: In function ‘intel_fbdev_framebuffer’:
./drivers/gpu/drm/i915/display/intel_fbdev.h:32:16: error: ‘NULL’ undeclared (first use in this function)

./drivers/gpu/drm/i915/display/intel_fbdev.h:32:16: note: each undeclared identifier is reported only once for each function it appears in
   32 |         return NULL;
      |                ^~~~

Build fails if CONFIG_DRM_FBDEV_EMULATION is n, add missing header file.

Fixes: 9fa154f40eb6 ("drm/{i915,xe}: Run DRM default client setup")
