Nouveau - Sep 2024 - [PATCH v4 68/80] drm/nouveau: Run DRM default client setup

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The nouveau driver specifies a preferred color mode depending on
the available video memory, with a default of 32. Adapt this for
the new client interface.

v2:
- style changes

I assume you can push this to drm-misc-next yourself?
