dmaengine: zynqmp_dma: fix burst length configuration
[ Upstream commit cc88525ebffc757e00cc5a5d61da6271646c7f5f ]
Since the dma engine expects the burst length register content as
power of 2 value, the burst length needs to be converted first.
Additionally add a burst length range check to avoid corrupting unrelated
register bits.
