dmaengine: fsl-dpaa2-qdma: Fix the size of dma pools
[ Upstream commit b73e43dcd7a8be26880ef8ff336053b29e79dbc5 ]
In case of long format of qDMA command descriptor, there are one frame
descriptor, three entries in the frame list and two data entries. So the
size of dma_pool_create for these three fields should be the same with
the total size of entries respectively, or the contents may be overwritten
by the next allocated descriptor.
