gpu: nvgpu: Implement a vidmem allocator
Implement an allocator suitable for managing the video memory on dGPUs.
It works by allocating chunks from an underlying buddy allocator and
collating the chunks together (similar to what an sgt does in the
wider Linux kernel). This handles the ability to get large buffers in
potentially fragmented memory. The GMMU can then obviously map the
physical vidmem into contiguous GVA spaces.
