Subject: [PATCH] lib: include <linux/io.h> for devmem_is_allowed definition

The devmem_is_allowed() is defined in <asm/io.h> but this or <linux/io.h>
is not included in lib/devmem_is_allowed.c does not include it. Fix the
following sparse warning by including <linux/io.h>

lib/devmem_is_allowed.c:20:5: warning: symbol 'devmem_is_allowed' was not declared. Should it be static?
