drm/amdgpu: Fix page table setup on Arcturus

When translate_further is enabled, page table depth needs to
be updated. This was missing on Arcturus MMHUB init. This was
causing address translations to fail for SDMA user-mode queues.

Fixes: 352e683b ("drm/amdgpu: Enable translate_further to extend UTCL2 reach")
