Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.
Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.

The kirin drivers uses drm_gem_cma_dumb_create_internal() for its
.dumb_create implementation. The function is meant for internal use
only by drivers that require additional buffer setup.
Kirin does not do an additional setup, so convert it over to
drm_gem_cma_dumb_create().

Daniel noted[1] that commit d606dc9a63 ("drm: kirin: Add
register connect helper functions in drm init") was unnecessary
and incorrect, as drm_dev_register does register connectors for
us.
Thus, this patch reverts the change as suggested by Daniel.

This reverts commit ff57c65138.
With the commit ff57c65138 ("drm: kirin: Fix for hikey620
display offset problem") we added support for handling LDI
overflows by resetting the hardware.
However, its been observed that when we do hit the LDI overflow
condition, the irq seems to be screaming, and we do nothing but
stream:
[drm:ade_irq_handler [kirin_drm]] *ERROR* LDI underflow!
over and over to the screen
I've tried a few appraoches to avoid this, but none has yet
been successful and the cure here is worse then the original
disease, so revert this for now.

Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:
- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.
- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.
- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).
In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).
Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.
The change is based on the following semantic patch, with manual review
and edits.

TTM is an implementation detail of the VRAM helpers and therefore
shouldn't be exposed to the callers. There's only one correct value
for the BO device anyway, which is the one stored in the DRM device.
So remove struct ttm_bo_device from the VRAM-helper interface and
use the device's VRAM manager unconditionally. The GEM initializer
function fails if the VRAM manager has not been initialized.

This patch implements prepare_fb() and cleanup_fb() in hibmc with the
GEM VRAM helpers. In the current code, pinning the BO is performed by
hibmc_plane_atomic_update(), where the operation does not belong.
This patch also fixes a bug where the pinned BO was never unpinned.
Pinning multiple BOs would have exhaused the available VRAM and further
pin operations would have failed, leaving the display in a corrupt
state.

drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,

Hisilicon developed hibmc_drm for their arm64 based soc and did not
intend for this driver to be used on any other architecture than arm64.
Using it on amd64 leads to incorrect video modes being used, making
the screen unreadable, forcing users to manually blacklist the module
on the kernel command line to use the d-i server installer or any
graphical sessions.
Make CONFIG_DRM_HISI_HIBMC firmly depend on ARM64 to ensure it is not
built for other architectures.

kirin_drm_private, and moves crtc_init and plane_init to
kirin drm drv too. Now that they are generic the functions
can be shared between the kirin620 and (to be added later)
kirin960 specific support code.
