drm/amd/display: fix num_ways overflow error
[Why]
Helper function calculates num_ways using 32-bit. But is
returned as 8-bit. If num_ways exceeds 8-bit, then it
reports back the incorrect num_ways and erroneously
uses MALL when it should not
[How]
Make returned value 32-bit and convert after it checks
against caps.cache_num_ways, which is under 8-bit
