If we don't have enough memory for ->planes then we leak "fb".

A lot of the modern userspace is capable of working without the legacy
fbdev support. kmscon can be used as a replacement for the framebuffer
console, and KMS X drivers create their own framebuffers.
Most people don't have a system where all of this works yet, though, so
leave support enabled by default.

The fbdev screen memory pointer is annotated __iomem, so cast the kernel
virtual address to that address space to make the warning go away.

The gr3d engine renders images bottom-up. Allow buffers that are used
for 3D content to be marked as such and implement support in the display
controller to present them properly.

The gr2d and gr3d engines work more efficiently on buffers with a tiled
memory layout. Allow created buffers to be marked as tiled so that the
display controller can scan them out properly.

drm_fbdev_cma_init does the inital fbcon setup by calling down into
drm_fb_helper_initial_config, so no need at all to restore the just
set up configuration right away ...

This commit adds a KMS driver for the Tegra20 SoC. This includes basic
support for host1x and the two display controllers found on the Tegra20
SoC. Each display controller can drive a separate RGB/LVDS output.
