Under "arm/mach-exynos" many files are using PMU register offsets. Since we have added support for accessing PMU base address via DT, now we can remove PMU mapping from exynosX_iodesc. Let's convert all these access using iomapped address. This will help us in removing static mapping of PMU base address as well as help in reducing dependency over machine header files. Thus helping for migration of PMU implementation from machine to driver folder which can be reused for ARM64 based SoC. Also as we have removed static mappings from "regs-pmu.h" it does not need map.h anymore. But "platsmp.c" needed this and till now it got included indirectly. So lets move header inclusion of "mach/map.h" from "regs-pmu.h" to "platsmp.c".
