drm/amdgpu/ih7.0: Enable retry CAM on Navi 4 dGPUs

Browse source

The retry CAM can filter interrupts which occur repeatedly,
such as page fault interrupts when retry faults are enabled.
This makes processing those interrupts much more efficient,
because the CPU won't have to deal with processing the same
interrupt repeatedly.

Also change the doorbell range to actually enable the
doorbell for the retry CAM.
