From: Luben Tuikov <luben.tuikov@xxxxxxx>
Convert to using devm_drm_dev_alloc(),
as drm_dev_init() is going away.
v2: Remove drm_dev_put() since
a) devres doesn't do refcounting, see
Documentation/driver-api/driver-model/devres.rst,
Section 4, paragraph 1; and since
b) devres acts as garbage collector when
the DRM device's parent's devres "action" callback
is called to free the container device (amdgpu_device),
which embeds the DRM dev.
