drm/amd/display: Initialize denominators' default to 1

Browse source

[ Upstream commit b995c0a6de ]

[WHAT & HOW]
Variables used as denominators and maybe not assigned to other values,
should not be 0. Change their default to 1 so they are never 0.

This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.
