For the ux500v2 variant of the PL18x block, non power of two block sizes are now supported.
In addition constraints on buffer alignments is needed since access to the PL18x FIFO must be done on a 4-byte aligned manner. Moreover to be able to use DMA for buffers with not 32 bytes aligned sg element lengths, DMAREQCTL must enabled.
