If we have more than 4 displays we will run
into dummy irq calls or flip timout issues.

d9e32672a1 drm/amd/display: cleanup of construct and destruct funcs
[Why]
Too many construct functions which makes searching
difficult, especially on some debuggers.

[How]
Append all construct and destruct functions with dcn
number and object type to make each construct function
name unique

e40837afb9 drm/amd/display: Register VUPDATE_NO_LOCK interrupts for DCN2
[Why]
These are needed to send back DRM vblank events in the case where VRR
is on. Without the interrupt enabled we're deferring the events into the
vblank queue and userspace is left waiting forever to get back the
events they need.

Found using igt@kms_vrr - the test fails immediately due to vblank
timeout.

[How]
Register them the same way we're handling it for DCN1.

This fixes igt@kms_vrr for DCN2.

b37727fb14 drm/amd/display: Add vupdate interrupt sources to NV10
[WHY] linux upstream already has interrupt vupdate for freesync
in dcn10. dcn20 interrupt shares the same source code as dcn10.
but dcn20 interrupt translator does not add vupdate interrupt.
this cause index of vupdate aarray be negative which causes
crash.

[HOW] add vupdate into dc interrupt transltor
