0790925dad drm/{i915,xe}/fbdev: add intel_fbdev_fb_pitch_align() 
For reasons still unknown, xe appears to require a stride alignment of
XE_PAGE_SIZE, and using 64 leads to sporadic failures. Go back to having
separate stride alignment for i915 and xe, until the issue is root
caused.

v2: Add FIXME comment, reference issue with Link (Ville)

5c3a68857d drm/{i915, xe}/fbdev: pass struct drm_device to intel_fbdev_fb_fill_info() 
This code is in fact driver core rather than display specific. Pass
struct drm_device instead of struct intel_display.

f379035fdf drm/{i915,xe}/fbdev: deduplicate fbdev creation 
With the bo creation helper in place, we can lift
intel_framebuffer_create() part to common code.

a170c6ca8b drm/{i915, xe}/fbdev: add intel_fbdev_fb_bo_destroy() 
i915 and xe do different things on the failure path; i915 calls
drm_gem_object_put() while xe calls xe_bo_unpin_map_no_vm(). Add a
helper to enable further refactoring.

v2: Call drm_gem_object_put() on intel_fbdev_fb_bo_destroy()
