drm/msm/dpu: fix x1e80100 intf_6 underrun/vsync interrupt

commit ce55101e6ba188296dbdb9506665d26f23110292 upstream.

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.
