maxwell_dma: Rename registers to match official docs and reorder
Rename registers in the MaxwellDMA class to match Nvidia's official documentation. This one can be found here: https://github.com/NVIDIA/open-gpu-doc/blob/master/classes/dma-copy/clb0b5.h While we are at it, reorganize the code in MaxwellDMA to be separated in different functions.
