I'm very happy to drop all this code if possible, but the stated reason
is not good enough. Rather we should look at the worst case and make
sure that 2 FIFO slots are enough for 180 MPixel/s on i.MX5 and enough
for 240 MPixel/s on i.MX6.
According to the current heuristic (total bandwidth = clkrate * 4 pixels
with 8 slots) that should be true.

regards
Philipp
