UPSTREAM: linux/io.h: import generic ioread* / iowrite* accessors from Linux
Some drivers in Linux (ex. drivers/mtd/nand/denali.c) use
ioread*/iowrite* accessors. Import them to make drivers more
synced. I copied code from include/asm-generic/io.h of Linux.

linux/io.h: add generic ioremap()/iounmap() defines
For most of architectures in U-Boot, virtual address is straight
mapped to physical address. So, it makes sense to have generic
defines of ioremap and friends in <linux/io.h>.
All of them are just empty and will disappear at compile time, but
they will be helpful to implement drivers which are counterparts of
Linux ones.
I notice MIPS already has its own implementation, so I added a
Kconfig symbol CONFIG_HAVE_ARCH_IOREMAP which MIPS (and maybe
Sandbox as well) can select.

In the latest Linux coding style, <linux/io.h> should be included
rather than <asm/io.h>. To follow this standard also in U-Boot,
add include/linux/io.h. Currently, it just includes <asm/io.h>.
