drm/radeon: Fix overflow of watermark calcs at > 4k resolutions.
Commit e6b9a6c84b93
("drm/radeon: Make display watermark calculations more accurate")
made watermark calculations more accurate, but not for > 4k
resolutions on 32-Bit architectures, as it introduced an integer
overflow for those setups and resolutions.
Fix this by proper u64 casting and division.
