The patch fixes the following compiler's warning:
In file included from include/common.h:33:0,
from arch/arm/mach-zynq/zynq.c:18:
arch/arm/include/asm/io.h:4:0: warning: "IO_SPACE_LIMIT" redefined
#define IO_SPACE_LIMIT 0
In file included from
arch/arm/mach-zynq/zynq.c:17:0:
include/asm-generic/io.h:92:0: note: this is the location of the previous definition
#define IO_SPACE_LIMIT 0xffff

This patch rely on other headers to pull in <asm/io.h>.
As zynq.c uses a lot of functions from <asm/io.h> then
using an explicit include would be better.
Just my opinion, you could argue this is bikeshedding.

asm-generic/io.h shouldn't be included directly, but only from asm/io.h
if it decides to do so. io.h includes asm/io.h, so this is the one that
should be included instead.

common.h includes asm/io.h, please see full patch context:

The question is, should we just drop this "#include <asm-generic/io.h>" or
change "#include <asm-generic/io.h>" into "#include <io.h>".

Since this file really uses readl and friends I'd say let's change it to
"#include <io.h>" rather than removing the inclusion.
