drm/msm/dpu: drop rogue intr_tear_rd_ptr values

The commit 5a9d50150c2c ("drm/msm/dpu: shift IRQ indices by 1") shifted
IRQ indices by 1, making 'NO_IRQ' to be 0 rather than -1 (and allowing
to skip the definition if the IRQ is not present).
Several platform files were sketched before that commit, but got applied
afterwards. As such, they inherited historical (and currently incorrect)
setting of .intr_tear_rd_ptr = -1 for 'NO_IRQ' value.

Drop that setting for all the affected platforms.
