From: Fabio Estevam <fabio.este...@freescale.com>
IPUv3 has a total of 3 flows (one synchronous flow and 2 asynchronous flows).
Let's add a definition for such number in order to let the code easier to
understand.

Changes since v1:
- Merged patches 4 and 5 from previous series
- Fix the comparison logic in 'if ((flow >> 1) >= IPUV3_NUM_FLOWS)'
