drm/fbdev-dma: Support struct drm_driver.fbdev_probe
Rework fbdev probing to support fbdev_probe in struct drm_driver
and reimplement the old fb_probe callback on top of it. Provide an
initializer macro for struct drm_driver that sets the callback
according to the kernel configuration.
This change allows the common fbdev client to run on top of DMA-
based DRM drivers.
