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. Make calcs more overflow resistant. This is a direct port of the corresponding patch from amdgpu-kms, copy-paste for cik from dce-8 and si from dce-6, with a slightly simpler variant for evergreen dce-4/5. Only tested on DCE-4 evergreen with a Radeon HD-5770.
