drm/radeon: Make display watermark calculations more accurate
Avoid big roundoff errors in scanline/hactive durations for
high pixel clocks, especially for >= 500 Mhz, and thereby
program more accurate display fifo watermarks.
This is a port of the corresponding amdgpu patch.
Implemented for DCE 4,6,8.
Tested on Evergreen/DCE-4 with Radeon HD-5770.
