Including <asm/cacheflush.h> from <asm-generic/io.h> prevents
cacheflush.h being able to use I/O functions like readl and writel due

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.

Who's tree should this go via.  I can take it via the openrisc tree, but
it would be good to get some Ack's that this isn't going to break things
for the other arch's (in particular score and unicore32, since they are
untested).
