No need for a home-grown version, the generic helper should work just
fine.  It also handles vgacon removal these days, see commit
1c74ca7a ("drm/fb-helper: call vga_remove_vgacon automatically."),
so that can be removed too.

Since commit b0e999c9 ("fbdev: list all pci memory bars as
conflicting apertures") the parameter was used for some sanity checks
only, to make sure we detect any issues with the new approach to just
list all memory bars as apertures.

No issues turned up so far, so continue to cleanup:  Drop the res_id
parameter, drop the sanity checks.  Also downgrade the logging from
"info" level to "debug" level and update documentation.

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames the
struct ade_crtc to kirin_crtc.

The struct kirin_crtc will later used by both kirin620 and
future kirin960 driver, and will be moved to a common
kirin_drm_drv.h in a future patch

As part of refactoring the kirin driver to better support
different hardware revisions, this patch removes the out_format
field in the struct ade_crtc, which was only ever set to
LDI_OUT_RGB_888.

Thus this patch removes the field and instead directly uses
LDI_OUT_RGB_888.

In a few functions, we pass in a struct ade_crtc, which we only
use to get to the underlying struct ade_hw_ctx.

Thus this patch refactors the functions to just take the
struct ade_hw_ctx directly.

The original HiKey (620) board has had a long running issue
where when using a 1080p montior, the display would occasionally
blink and come come back with a horizontal offset (usually also
shifting the colors, depending on the value of the offset%4).

After lots of analysis by HiSi developers, they found the issue
was due to when running at 1080p, it was possible to hit the
device memory bandwidth limits, which could cause the DSI signal
to get out of sync.

Unfortunately the DSI logic doesn't have the ability to
automatically recover from this situation, but we can get a an
LDI underflow interrupt when it happens.

To then correct the issue, when we get an LDI underflow irq, we
we can simply suspend and resume the display, which resets the
hardware.

Thus, this patch enables the ldi underflow interrupt, and
initializes a workqueue that is used to suspend/resume the
display to recover. Then when the irq occurs we clear it and
schedule the workqueue to reset display engine.

TTM assumes that drivers initialize the embedded GEM object before
calling the ttm_bo_init() function. This is not currently the case
in the Nouveau driver. Fix this by splitting up nouveau_bo_new()
into nouveau_bo_alloc() and nouveau_bo_init() so that the GEM can
be initialized before TTM BO initialization when necessary.
