[PATCH v4 0/6] drm/xe: Make struct xe_ggtt private.

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

Sent as a separate series.

I have merged the patches to make pt_ops and ggtt private, and reworked xe_fb_pin.c

xe_fb_pin.c had the problem that some parts belong there, while others belong to xe_ggtt,
I'm hoping that with the callback function to populate the GGTT node, I've fixed the layering
violation that would have to happen otherwise.

I've solved it by creating a xe_ggtt_node_insert_transform() function that calls back into xe_fb_pin.c
to populate a given xe_ggtt_node. This way xe_fb_pin can still write a rotated GGTT, while outside
the scope of this function the details are hidden.

Writing DPT requires the same encoding as GGTT, but since it's a normal bo it only needs access to the
GGTT encoding function. With the insert transformation function being the only way to write to GGTT,
it should be safe to export the encoding only.

The display quirks stay in xe_fb_pin.c, while the details of GGTT stay in xe_ggtt.c now!
