dmaengine: rcar-hpbdma: tidyup residue_granularity

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

The driver doesn't support residue reporting at all.
residue_granularity should be set to DMA_RESIDUE_GRANULARITY_DESCRIPTOR.
Special thanks to Laurent
