BCM5719 cannot handle DMA requests for DMA segments that have
larger than 4KB in size. However the maximum DMA segment size
created in DMA tag is 4KB, so we wouldn't encounter the issue here.
Just record this issue such that let developers not to create a DMA
segment that is larger than 4KB for BCM5719. It's possible to split
a DMA segment into multiple smaller ones in run time but I believe
it's not worth to implement that.
