Ivan Lipski 29a2f43047 drm/amd/display: Allow RX6xxx & RX7700 to invoke amdgpu_irq_get/put
[Why&How]
As reported on https://gitlab.freedesktop.org/drm/amd/-/issues/3936,
SMU hang can occur if the interrupts are not enabled appropriately,
causing a vblank timeout.

This patch reverts commit 5009628d85 ("drm/amd/display: Remove unnecessary
amdgpu_irq_get/put"), but only for RX6xxx & RX7700 GPUs, on which the
issue was observed.

This will re-enable interrupts regardless of whether the user space needed
it or not.

Fixes: 5009628d85 ("drm/amd/display: Remove unnecessary amdgpu_irq_get/put")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3936
