drm/amd/display: prevent potential division by zero errors
commit 07e388aab042774f284a2ad75a70a194517cdad4 upstream.
There are two places in apply_below_the_range() where it's possible for
a divide by zero error to occur. So, to fix this make sure the divisor
is non-zero before attempting the computation in both cases.
