Re: [RFT 03/13] sh: Constify ioreadX() iomem argument (as in generic implementation)

The ioreadX() helpers have inconsistent interface.  On some architectures
void *__iomem address argument is a pointer to const, on some not.

Implementations of ioreadX() do not modify the memory under the address
so they can be converted to a "const" version for const-safety and
consistency among architectures.

The patch looks good, but I think this has to be done together with the powerpc
version and the header that declares the function, for bisectibility.
