[PATCH] dmaengine: rcar-dmac: read DMATCRB instead of DMATCR for residue

From: Kuninori Morimoto SYS/RT/Audio DMAC have both TCR/TCRB register. Its difference is transfer counter value of read (= TCR) or write (= TCRB). The relationship is like below. TCR TCRB [SOURCE] -> [DMAC] -> [DESTINATION] Thus, we want to

From: Kuninori Morimoto SYS/RT/Audio DMAC have both TCR/TCRB register. Its difference is transfer counter value of read (= TCR) or write (= TCRB). The relationship is like below. TCR TCRB [SOURCE] -> [DMAC] -> [DESTINATION] Thus, we want to read TCRB instead of TCR for residue.
