Store both MMIO bases as a plain void __iomem * and derive jrregs with void __iomem * arithmetic from re_regs, rather than carrying typed register struct pointers through the driver. Each function that touches the registers introduces a local typed pointer (struct fsl_re_ctrl __iomem *ctrl) and uses ->field, which is the idiomatic kernel pattern and keeps the registers' __iomem qualification intact.

This patch enables the RaidEngine functionality and provides hardware offloading capability for memcpy, xor and pq computation. It works with async_tx.
