[PATCH] drm/xe/display: Fix fbdev GGTT mapping handling.

[Maarten Lankhorst <dev@lankhorst.se>]

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.

Fixes: 67a98f7e27ba ("drm/xe/display: Re-use display vmas when possible")
