[PATCH v2 2/2] remoteproc/mediatek: fix sparse errors on dma_alloc and dma_free

[Tzung-Bi Shih]

Fixes the following sparse errors on dma_alloc_coherent() and
dma_free_coherent().

On drivers/remoteproc/mtk_scp.c:559:23:
warning: incorrect type in assignment (different address spaces)
   expected void [noderef] __iomem *cpu_addr
   got void *

On drivers/remoteproc/mtk_scp.c:572:56:
warning: incorrect type in argument 3 (different address spaces)
   expected void *cpu_addr
   got void [noderef] __iomem *cpu_addr

The cpu_addr is not a __iomem address.  Removes the marker.
