Because it is. Huge congrats to everyone who made this kind of
refactoring happen!

Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by roughly 70% I think it'll still be alot easier to review than a
longish baby-step patch series.
Changes summary:
- Given the small amout of video memory (4 MB) the cirrus device has
the rewritten driver doesn't try to manage buffers there. Instead
it will blit (memcpy) the active framebuffer to video memory.
- All gem objects are stored in main memory and are manged using the
new shmem helpers. ttm is out.
- It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24
or RG16 at blit time if needed, to avoid the pitch becoming larger
than what the cirrus hardware can handle.
- The simple display pipeline is used.
- The generic fbdev emulation is used.
- It's a atomic driver now.
- It runs wayland.

Include <drm/*.h> instead of relative path from include/drm, then
remove the -Iinclude/drm compiler flag.

This is the initial driver for emulated cirrus GPU found in qemu.
This driver only supports the emulated GPU and doesn't attempt
to bind to any real cirrus GPUs.
This driver is intended to be used with xf86-video-modesetting in userspace.
It requires at least version 0.3.0
This follow the same design as ast and mgag200, and is based on work
done by Matthew Garrett previously.
This GPU has no hw cursor, and it can't scanout 32-bpp, only packed 24-bpp.
i.e. it sucks.
