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.
