Mario Kleiner e190ed1ea7 drm/amdgpu: Avoid overflows/divide-by-zero in latency_watermark calculations.
At dot clocks > approx. 250 Mhz, some of these calcs will overflow and
cause miscalculation of latency watermarks, and for some overflows also
divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in
"dce_v10_0_latency_watermark+0x12d/0x190").

This zero-divide happened, e.g., on AMD Tonga Pro under DCE-10,
on a Displayport panel when trying to set a video mode of 2560x1440
at 165 Hz vrefresh with a dot clock of 635.540 Mhz.

Refine calculations to avoid the overflows.

Tested for DCE-10 with R9 380 Tonga + ASUS ROG PG279 panel.

Mario Kleiner d63c277dc6 drm/amdgpu: Make display watermark calculations more accurate
Avoid big roundoff errors in scanline/hactive durations for
high pixel clocks, especially for >= 500 Mhz, and thereby

Implemented here for DCE 6,8,10,11.

Christopher James Halse Rogers 803d89ade4 drm/amdgpu: Refuse to pin or change acceptable domains of prime BOs to VRAM. (v2)
Migration to VRAM will break the sharing, resulting in rendering on the exporting GPU never becoming
