The IRQ indexes for the intf_6 underrun/vsync interrupts are swapped. DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 16) is the actual underrun interrupt and DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 17) is the vsync interrupt.
This causes timeout errors when using the DP2 controller, e.g. [dpu error]enc37 frame done timeout *ERROR* irq timeout id=37, intf_mode=INTF_MODE_VIDEO intf=6 wb=-1, pp=2, intr=0 *ERROR* wait disable failed: id:37 intf:6 ret:-110
Correct them to fix these errors and make DP2 work properly.

This fixes the errors I was seeing with the third usb-c port on the x1e80100 CRD:
