[PATCH v3 17/21] drm/msm/dpu: Describe TEAR interrupt registers for DSI interfaces

[Marijn Suijten <marijn.suijten@xxxxxxxxxxxxxx>]

All SoCs since DPU 5.0.0 have the tear interrupt registers moved out of
the PINGPONG block and into the INTF block.  Wire up the IRQ register
masks in the interrupt table for enabling, reading and clearing them.
