[PATCH 6.12.y 2/3] drm/panel-mipi-dbi: Run DRM default client setup

[Fabio Estevam <festevam@gmail.com>]

From: Thomas Zimmermann <tzimmermann@suse.de>

commit 1b0caa5f5ac20bcaf82fc89a5c849b21ce3bfdf6 uptream.

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.

v5:
- select DRM_CLIENT_SELECTION
