[PATCHv2] dmaengine: fsl_raid: switch __b32 to u32

[Rosen Penev]

The register maps in fsl_raid.h annotate every field as __be32, but
they are accessed only through ioread32be()/iowrite32be(), which
already perform the byte swap and take plain u32 __iomem pointers.
The __be32 annotation therefore makes sparse reject each access:

  drivers/dma/fsl_raid.c:116:17: sparse: incorrect type in argument 1
      (different base types) ... got restricted __be32 [noderef] __iomem *

Drop __be32 from struct fsl_re_ctrl and struct fsl_re_chan_cfg; the
descriptor/CDB structures written via cpu_to_be32() keep their
annotations.
