Isabel Zhang 685b4d8142 drm/amd/display: Force prefetch mode to 0
[Why]
On APU should be always using prefetch mode 0.
Currently, sometimes prefetch mode 1 is being
used causing system to hard hang due to
minTTUVBlank being too low.

[How]
Any ASIC running DCN21 will by default allow
self refresh and mclk switch. This sets both
min and max prefetch mode to 0 by default.
