In several cases the drmP.h include could be removed without
furter fixes. Other files required a few header files to be added.

The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.
In places where is might be necessary, the current behaviour of cleaning the
pointer is kept.

It makes more sense to have all the buffer object related code in
a single file rather than splitting it up between the resource code
and buffer object pinning utilities.
Place all buffer object related code in vmwgfx_bo.c. Fix up headers
and export resource functionality when needed in the buffer object
code.

This patch address the following underlying issues with SurfaceDMA
* SurfaceDMA command does not work in a 2D VM, but we can wrap a
proxy surface around the same DMA buffer and use the SurfaceCopy
command which does work in a 2D VM.
* Wrapping a DMA buffer with a proxy surface also gives us an
added optimization path for the case when the DMA buf
dimensions match the mode. In this case, the DMA buf can
be pinned as the display surface, saving an extra copy.
This only works in a 2D VM because we won't be doing any
rendering operations directly to the display surface.
v2
* Moved is_dmabuf_proxy field to vmw_framebuffer_surface
* Undone coding style changes
* Addressed other issues from review

This commit reworks device initialization so that we always enable the
FIFO at driver load, deferring SVGA enable until either first modeset
or fbdev enable.
This should always leave the fifo properly enabled for render- and
control nodes.
In addition,
*) We disable the use of VRAM when SVGA is not enabled.
*) We simplify PM support so that we only throw out resources on hibernate,
not on suspend, since the device keeps its state on suspend.
