drmPrimeFDToHandle directly. Mention GBM as a solution.

If a device has a primary node, it doesn't necessarily mean it's
suitable for KMS usage. For instance, render-only drivers also
expose primary nodes.
The check is extracted from Weston [1].
The motivation for this new function is two-fold:
- Avoid an unnecessary GETRESOURCES call. To check whether a
primary node is suitable for KMS, we don't actually need to
retrieve the object IDs we just need to check the counts.
- Avoid confusion in user-space and make sure user-space implements
the check properly. For instance, wlroots doesn't [2]: it uses
drmGetVersion which succeeds with render-only drivers.

When and which headers to update?
If the kernel uapi drm header changes, the header here should be sync-ed.
When and how to update these files
The steps for generating this patch:
- Switch to freedesktop drm-next kernel branch (https://cgit.freedesktop.org/drm/drm);
- Install the headers via `make headers_install';
- Copy from kernel "include/uapi/drm/amdgpu_drm.h" to libdrm "include/drm/amdgpu_drm.h";
- generate the patch;

I don't exactly know why these were duplicated before. Maybe libdrm
didn't always vendored drm_mode.h from the kernel? In any case, we now
do, so instead of having copy-pasted definitions, just include our
vendored version which cannot be outdated.
Contrary to what the comment says, drm.h doesn't include drm_mode.h, so
we need to add the include.

DMA's atomic behavir is unlike GFX,If the comparing data is not
equal to destination data,
For GFX, loop again till gfx timeout(system hang).
For DMA, loop again till timer expired and then send interrupt.
So testcase can't use interrupt mechanism.
We take another way to verify. When the comparing data is not
equal to destination data, overwrite the source data to the destination
buffer. Otherwise, original destination data unchanged.
So if the bo_cpu data is overwritten, the result is passed.
Steps:
1. use linear write packet to write 0xdeadbeaf to secure buffer,
2. use atmoic packet and ATOMIC_CMPSWAP_RTN_32 opcode to compare
the cmp_data(0xdeadbeaf) to the written data which has been encrypted.
v2: add the case of (dest_data != cmp_data).

Secure buffer is only able to be read with trusted ip block.
So we need use GFX ip to read it back instead of CPU.

1. use write_data packet to write 0xdeadbeaf to secure buffer,
2. use atmoic_mem packet and ATOMIC_CMPSWAP_RTN_32 opcode to compare
the cmp_data(0xdeadbeaf) to the written data which has been encrypted.
If the result is equal, then overwrite the src_data(0x12345678) to the
secure buffer and return directly. Otherwise loop again until gfx timeout
and the secure buffer data unchanged.
