Re: [PATCH 2/6] nfit: Fix up address spaces, sparse warnings

Fix a couple of sparse warnings (duplicate const, incorrect address space), and go back to using memcpy() instead of memcpy_toio() and memcpy_fromio() when talking to our block apertures. Instead, include a union to alias mmio->base and mmio->aperture so that we can continue to reuse common code for ioremapping and deinterleaving. mmio->base still has the __iomem annotation and is used via readq() and writeq() for the control and status registers. mmio->aperture is used via normal memcpy() for aperture I/O.
