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.
