drm/xe/display: Fix fbdev GGTT mapping handling.

Browse Source 
FBDEV ggtt is not restored correctly, add missing GGTT flag to
intel_fbdev_fb_alloc to make it work. This ensures that the global
GGTT mapping is always restored on resume. The GGTT mapping would
otherwise be created in intel_fb_pin_to_ggtt() by intel_fbdev anyway.

This fixes the fbdev device not working after resume.
