Having an explicit init of interrupt fields to -1 for not existing IRQs
makes it easier to forget and/or miss such initialisation, resulting in
a wrong interrupt definition.

Instead shift all IRQ indices to turn '0' to be the non-existing IRQ.

Dependencies: [1]

Changes since v2:
 - Added the dpu_core_irq_is_valid() helper
 - Replaced irq_idx with reg/big pairs in kernel output
 - Readded -1 when accessing the IRQ structure.

Changes since v1:
 - Rebased on top of msm-next-lumag and updated IRQ rework series.

Dmitry Baryshkov (6):
  drm/msm/dpu: remove irq_idx argument from IRQ callbacks
  drm/msm/dpu: extract dpu_core_irq_is_valid() helper
  drm/msm/dpu: add helper to get IRQ-related data
  drm/msm/dpu: make the irq table size static
  drm/msm/dpu: stop using raw IRQ indices in the kernel output
  drm/msm/dpu: shift IRQ indices by 1
