Steve Longerbeam dd916eb6cf gpu: ipu-v3: image-convert: Wait for all EOFs before completing a tile 
[ Upstream commit dd81d821d0b3f77d949d0cac5c05c1f05b921d46 ]

Use a bit-mask of EOF irqs to determine when all required idmac
channel EOFs have been received for a tile conversion, and only do
tile completion processing after all EOFs have been received. Otherwise
it was found that a conversion would stall after the completion of a
tile and the start of the next tile, because the input/read idmac
channel had not completed and entered idle state, thus locking up the
channel when attempting to re-start it for the next tile.
