drm/amd/display: Correct min comp buffer size

Browse source

[Why]
In 3-way mpo pipes, there is a case that we
overbook the CRB buffer size. At rare instances,
overbooking the crb will cause underflow. This only
happens when det_size changes dynamically
based on pipe_cnt.

[How]
Set min compbuff size to 1 segment when preparing BW.
