Subject: [PATCH] DMA: shdma: fix compiler warning after a bad merge

A recent merge commit

commit ba1e06e3dff9a0bb0758d169e50cbb04a67a402c
Author: Vinod Koul <vinod.koul@...el.com>

    Merge branch 'topic/sh' into next

introduced a compiler warning:

drivers/dma/sh/shdmac.c: In function 'sh_dmae_probe':
drivers/dma/sh/shdmac.c:697: warning: assignment discards qualifiers from pointer target type

This patch re-adds the dropped "const" qualifier and fixes the warning.
