drm/amd/display: Fix possible overflow in integer multiplication
[WHAT & HOW]
Integer multiplies integer may overflow in context that expects an
expression of unsigned/siged long long (64 bits). This can be fixed
by casting integer to unsigned/siged long long to force 64 bits results.
This fixes 26 OVERFLOW_BEFORE_WIDEN issues reported by Coverity.
