drm/amdgpu: enable ih1 ih2 for Arcturus only

Browse Source 
Enable multi-ring ih1 and ih2 for Arcturus only.
For Navi10 family multi-ring has been disabled.
Apparently, having multi-ring enabled in Navi was causing
continus page fault interrupts.
Further investigation is needed to get to the root cause.
