gpu: nvgpu: Implement NVGPU_GPU_IOCTL_GET_BUFFER_INFO
Implement NVGPU_GPU_IOCTL_GET_BUFFER_INFO. The new IOCTL can be used
to identify buffers and retrieve their sizes. This allows the
userspace to be agnostic to the dmabuf implementation, as the generic
dmabuf fd interface does not have a reliable way for buffer
identification.
