Subject: [PATCH v1] drm/msm/dpu: Fix address of SM8150 PINGPONG5 IRQ register

Both PINGPONG4 and PINGPONG5 IRQ registers are using the
same address, which is incorrect. PINGPONG4 should use the
register offset 30, and PINGPONG5 should use the register
offset 31 according to the downstream driver.

Fixes: 667e9985ee24 ("drm/msm/dpu: replace IRQ lookup with the data in hw catalog")
