drm-tests: refactor nv12_test to use bsdrm and planes

This test used to use the atrocious "sp" library. This CL removes that
dependency by using bsdrm, gbm, and its own drawing code. In particular,
the usage of gbm and bsdrm enhance this test because gbm uses hardware
specific knowledge to generate properly aligned buffer objects, and
bsdrm will automatically make proper framebuffers out of them.

In addition, this test transitions to using an overlay plane to output a
NV12 surface. The hardware that was used to test this change only
supports the NV12 on planes.

CHROMIUM: drm/rockchip: enable plane scaling

The VOP can handle scaling up or down by up to a factor of 8. Sadly, it
does not seem to handle vertical scale down factors near 2, 4, or 8.
This CL includes a workaround to slightly reduce the src height to
ensure the degenerate case is avoided.

rockchip: add NV12 bo creation support

This patch does alignment if needed on the width and height, but does
not expose this change to the public facing gbm_bo. It is expected that
framebuffer creation in the kernel with do alignment such that
applications don't have to have platform specific knowledge of alignment
requirements.

drm-tests: mv nv12_test to plane_test and support more formats

What's better than nv12_test? A test that can write to an unbounded
number of formats is what. This patch lays out the groundwork for easily
adding more formats to draw to. It also allows the user of plane_test to
pass in the desired format as the first argument.

drm-tests: plane_test: add more options for testing planes

Hardware overlay planes are complex and it's often required to test
specific features individually when debugging them. This change adds
options to translate, scale, and crop planes. It also allows multiple
planes to be used at the same time in order to test their interactions.

Activating. Please assign to the right owner and the appropriate priority.

Let close this. We have nv12 support in core chromeos and support in kms on some boards. We'll track future enabling for specific platforms in their own new bugs.
