Luben Tuikov 1348969ab6 drm/amdgpu: drm_device to amdgpu_device by inline-f (v2)
Get the amdgpu_device from the DRM device by use
of an inline function, drm_to_adev(). The inline
function resolves a pointer to struct drm_device
to a pointer to struct amdgpu_device.

v2: Use a typed visible static inline function
    instead of an invisible macro.
