asm-generic/io.h: remove asm/cacheflush.h include
Including <asm/cacheflush.h> from <asm-generic/io.h> prevents cacheflush.h being able to use I/O functions like readl and writel due to circular include dependencies. It doesn't appear as if anything from cacheflush.h is actually used by the generic io.h, so remove the include. I've compile tested a defconfig compilation of blackfin, openrisc (which needed <asm/pgtable.h> including from it's <asm/io.h> to get the PAGE_* definitions), and xtensa. Other architectures which use asm-generic/io.h are score and unicore32, and looking at their io.h I don't see any obvious problems.
