Wang Fudong 3e834a17a2 drm/amd/display: set dig fifo read start level to 7 before dig fifo reset
[Why]
DIG_FIFO_ERROR = 1 caused mst daisy chain 2nd monitor black.

[How]
We need to set dig fifo read start level = 7 before dig fifo reset during dig
fifo enable according to hardware designer's suggestion. If it is zero, it will
cause underflow or overflow and DIG_FIFO_ERROR = 1.
