disp: msm: sde: Fix 32-bit compilation issues

1.Typecast to avoid distinct pointer type comparison
2.Keep DMA mask aligned with api definition.
3.Add Suffix for literals
4.Remove multfrac func to avoid uncompatible division.
5.64-bit division( operator "/") on 32-bit platforms is not supported.
  Using platform independent API's here
