drm/amd/display: Fix HPD after gpu reset
commit 4de141b8b1b7991b607f77e5f4580e1c67c24717 upstream.
[Why]
DC is not using amdgpu_irq_get/put to manage the HPD interrupt refcounts.
So when amdgpu_irq_gpu_reset_resume_helper() reprograms all of the IRQs,
HPD gets disabled.
[How]
Use amdgpu_irq_get/put() for HPD init/fini in DM in order to sync refcounts
