This patch adds ioremap_wt() to all arch-specific asm/io.h which

include <asm-generic/iomap.h>. Some of them include
<asm-generic/io.h>, but ioremap_wt() is defined for consistency
since they define all ioremap_xxx locally.
ioremap_wt() is defined indentical to ioremap_nocache() to all
architectures without WT support.
frv and m68k already have ioremap_writethrough(). This patch
implements ioremap_wt() indetical to ioremap_writethrough() and
defines ARCH_HAS_IOREMAP_WT in both architectures.
This wants a follow up patch, which replaces ioremap_writethrough() in
drivers/ with ioremap_wt and removes ioremap_writethrough() from arch/
