Subject: [PATCH] drm/amd/display: Remove ASSERT if significance is zero in
 math_ceil2

In the DML math_ceil2 function, there is one ASSERT if the significance
is equal to zero. However, significance might be equal to zero
sometimes, and this is not an issue for a ceil function, but the current
ASSERT will trigger warnings in those cases. This commit removes the
ASSERT if the significance is equal to zero to avoid unnecessary noise.
