drm_crtc.h has no need for linux/fb.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching linux/fb.h.

Quite a few placs do currently depend on linux/fb.h or other
headers pulled in by it without actually including any of it
directly. All of those need to be fixed up.

v2: Split the vmwgfx change out

<title>drm: omapdrm: Do no allocate non-scanout GEMs through DMM/TILER</title>

On devices with DMM, all allocations are done through either DMM or TILER.
DMM/TILER being a limited resource means that such allocations will start
to fail before actual free memory is exhausted. What is even worse is that
with time DMM/TILER space gets fragmented to the point that even if we have
enough free DMM/TILER space and free memory, allocation fails because there
is no big enough free block in DMM/TILER space.

Such failures can be easily observed with OMAP xorg DDX, for example -
starting few GUI applications (so buffers for their windows are allocated)
and then rotating landscape&lt;-&gt;portrait while closing and opening new
windows soon results in allocation failures.

Fix that by mapping buffers through DMM/TILER only when really needed,
like, for scanout buffers.

<title>drm: omapdrm: Support exporting of non-contiguous GEM BOs</title>

<id>1948d28db6215d055930f0cbb6e300622ede5931</id>
<content type='text'>
Currently code allocates non-scanout BOs from SHMEM and those objects are
accessible to userspace by mmap(). However, on devices with no DMM (like
OMAP3), the same objects are not accessible by kernel drivers that want to
render to them as code refuses to export them. In turn this means that on
devices with no DMM, all buffers must be allocated as scanout, otherwise
only CPU can access them. On those devices, scanout buffers are allocated
from CMA, making those allocations highly unreliable.

Fix that by implementing functionality to export SHMEM backed buffers on
devices with no DMM. This makes CMA memory only being used when needed,
instead for every buffer that has to be off-CPU rendered.

Tested on Motorola Droid4 and Nokia N900
