Several platforms create IOMEM defines for casting to 'void __iomem *', and other platforms are incorrectly using __io() macro for the same purpose. This creates a common definition and removes all the platform specific versions. Rather than try to make linux/io.h and asm/io.h assembly safe, the assembly version of IOMEM is moved into asm/assembler.h.
