This patch does the below:
1. Adds DRM_FORMAT_NV12 & DRM_FORMAT_NV21
to the list of formats supported by amdgpu driver
2. bo_create() updates parameter's of video planes
appropriately.
3. add DRM_FORMAT_NV21 in drv.c & helpers.c
This patch is a step towards enabling overlay based video rendering
capability available in hardware.

When doing alignment, many times we get the bytes per pixel, try
to align to a certain boundary, and then pass in the "aligned width"
to drv_bo_from_format. This back and forth is confusing and error
prone. Let's change our drivers and helpers to eliminate this, and
try to work in strides as soon as possible.
Additionally, let's make drv_bpp_from_format a static function. This
is because bits per pixel is ill-defined for YUV formats, and we should
work in strides whenever possible.

YV12 in <system/graphics.h> in the Android tree defines the

Let's keep a count of how many times a buffer has been locked, since
we have special lock_ycbcr() behavior that returns the offsets and
strides of a YUV buffer when an usage of zero is passed in. This behavior
is used by the ArcCodec. We have to take care not to call drv_bo_unmap
if we didn't map anything.
We also have to expose struct map_info so we can return the address if
we have mapped data, rather than incrementing the drv map count.
Additionally, the gralloc.h says:
"THREADING CONSIDERATIONS
It is legal for several different threads to lock a buffer from
read access, none of the threads are blocked."
This implies recursive locking, which this commit implements.

We've been back and forth on the semantics of the flag API many
times, and the current situation is confusing.
Change the drivers so every combination defines a distinct type of
buffer. That means if the same format is in the combination list three
times, the tiling or format modifiers of one of those combinations must
be different from the other two.
Let's add a priority variable in struct supported_combination that
breaks ties. For example, if a consumer specifies BO_USE_TEXTURE,
we of course can texture from both linear and tiled buffers, but
because a tiled buffer's priority is greater, it will be chosen.
If a consumer specifies BO_USE_TEXTURE | BO_USE_SW_WRITE_OFTEN, the
tiled combination won't have the BO_USE_SW_WRITE_OFTEN flag and the
linear combination will be chosen.
We expect drivers to modify the combinations after querying KMS.
This is clunky using linked lists, so get rid of list.h and use arrays.

This adds support for allocating AFBC (ARM FrameBuffer Compression)
buffers with minigbm for Rockchip SoCs. AFBC buffers are allocated
through the new gbm_bo_create_with_modifiers() entry point. Callers are
responsible for determining which modifiers are valid for the intended
use case and pass in that list. gbm will then pick the optimal modifier
and allocate a buffer with that layout. The chosen modifier can be
queries through gbm_bo_get_format_modifier().
Callers of the new entry point are expected to forward the modifier when
using the buffer with other APIs (EGL, KMS etc). The old gbm_bo_create()
entry point continues to work as before and won't allocate AFBC buffers.

We were incorrectly advertising the scanout and cursor flags in

Chrome never used the BO_USE_CURSOR flag (see chromium:666488), and we
set it for incorrect formats. Let's only advertise ARGB8888/XRGB8888
cursors if they were previously advertised, and prevent cursors from being
used as render targets.
For scanout, formats can vary from kernel version to kernel version.
For example, the v3.18 i915 driver can't scanout NV12, but the upstream v4.4
i915 driver can. Let's query the KMS API in those cases.
In addition, we would also like to move to a place where our backends can
determine if a specific {format, usage, format modifier} tuple is supported.
The plan is to add modifiers to the properties that are exposed in KMS, which
can help with optimization.
