[PATCH 6.4 411/800] drm/msm/dpu: fix sc7280 and sc7180 PINGPONG done interrupts

[ Upstream commit 0b78be614c503ec03636f82cea52ad735c5085e7 ]

During IRQ conversion we have lost the PP_DONE interrupts for sc7280
platform. This was left unnoticed, because this interrupt is only used
for CMD outputs and probably no sc7[12]80 systems use DSI CMD panels.

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