[RFT 06/13] arc: Constify ioreadX() iomem argument (as in generic implementation)

2020-01-07 Thread Krzysztof Kozlowski
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
