Implement reclocking for DDR2, DDR3, GDDR3
Following a series of patches that implement memory reclocking for NVA3/5/8 with
DDR2, DDR3 and GDDR3 on board. I tested these patches on 6 different graphics
cards, but I expect reclocking now to work on many more.
Testers can pick up these patches and test it by enabling pstate
(nouveau.pstate=1). They should then be able to change clocks by writing to
/sys/class/drm/card0/device/pstate. Correct
