nvc0: Add NVE4 (Kepler) DMA COPY class documentation
Has been utilised within nouveau in place of the former
M2MF class, which was
dropped for Kepler in
PGRAPH in favour of:
- a new
P2MFobject that only does simple upload; and
PCOPYtook over responsibility of
M2MF's other DMA functions.
Autogenerated headers from envytools commit [ ] (under review, to be landed).
