The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().
The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

- best_encoder cleanup from Boris.
- drm_simple_display_pipe helpers from Noralf. Looks really neat imo, and
there's 2-3 in-flight drivers which look like they could/should use it.
Anyway, with this we have now helpers and everything in place to write
drivers for simple hw with fewer complexity in the driver than what
fbdev would need. That was the last complaint I've heard from embedded
folks after we made atomic happen. Mission accomplished!
- nonblocking commit helpers for atomic, plus a bunch of driver patches
for that.
- Prep patch from Laurent for cleaned up pixel format functions.
- More of Gustavo's cleanup for drm vblank functions.
- and a few oddball things in between
Plus the merge of docs-next to prep the docbook->sphinx conversion as
discussed. Jon cc'ed as fyi.

In case of simulation there's no real encoder/transmitter device
because in the model's virtual LCD we're rendering whatever
appears in frame-buffer memory.

This is just used for cleanup in preclose, and with the reworked event
handling code this is now done properly by the core.
Nuke it!
But it also shows that arc totally fails at sending out drm events for
flips. Next patch will hack that up.
v2: Rebase it!

ARC PGU could be found on some development boards from Synopsys.
This is a simple byte streamer that reads data from a framebuffer
and sends data to the single encoder.
