drm/amd/display: Force enable 3DLUT DMA check for dcn401 in DML
[WHY]
Currently TR0 (trip 0) is not properly budgeting for urgent latency in
DML2.1. This results in overly aggressive prefetch schedules that are
vulnerable to request return jitter, resulting in severe underflow at
the start of the frame.
[HOW]
Forcing 3DLUT DMA check to enable causes urgent latency to be budgeted
properly into the prefetch schedule, avoiding the vulnerability.

[Why]
We manage interrupts for CRTCs in two places:
1. In manage_dm_interrupts(), when CRTC get enabled or disabled
2. When drm_vblank_get/put() starts or kills the vblank counter, calling
into amdgpu_dm_crtc_set_vblank()
The interrupts managed by these twp places should be identical.
[How]
Since manage_dm_interrupts() already use drm_crtc_vblank_on/off(), just
move all CRTC interrupt management into amdgpu_dm_crtc_set_vblank().
This has the added benefit of disabling all CRTC and HUBP interrupts
when there are no vblank requestors.
Note that there is a TODO item - unchanged from when it was first
introduced - to properly identify the HUBP instance from the OTG
instance, rather than just assume direct mapping.
