arch/*/io.h: Add ioremap_wt() to all architectures
Add ioremap_wt() to all arch-specific asm/io.h headers which
define ioremap_wc() locally. These headers do not 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.
In all architectures without Write-Through support, ioremap_wt()
is defined indentical to ioremap_nocache().
frv and m68k already have ioremap_writethrough(). On those we
add ioremap_wt() indetical to ioremap_writethrough() and defines
ARCH_HAS_IOREMAP_WT in both architectures.
The ioremap_wt() interface is exported to drivers.
