drm/amd/display: Disable boot optimization for DCN401

Browse Source 
[Why]
DCN401 currently has an issue re-enabling when pipe splitting is enabled,
while the root cause is being investigated we can make sure everything is
being reset as a workaround, by disabling boot optimization.

[How]
 - use enable_accelerated_mode instead of init_pipes to fully reset asic
