ARM: shmobile: bockw: use HPBIF DMAEngine for sound
R-Car sound driver is supporting Mem <-> SRU <-> SSI transfer via DMAEngine. The sound will be less noise if it uses SRU path since it has FIFO. This patch supports it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
