drm/amd/display: log destination of vertical interrupt
[Why]
Knowing the destination of OTG's vertical interrupt 2 is useful for
debugging, but it is not currently included in the OTG state readback
logic
[How]
Read the OTG interrupt destination register to get the vertical interrupt
2 destination on ASICs that have this register when reading back the OTG
state from hardware
