This arch-independent routine copies data to a memory-mapped I/O region,
using 32-bit accesses. The naming is double-underscored to make it clear
that it does not guarantee write ordering, nor does it perform a memory
barrier afterwards; the kernel doc also explicitly states this. This style
of access is required by some devices.
This change also introduces include/linux/io.h, at Andrew's suggestion. It
only has one occupant at the moment, but is a logical destination for
oft-replicated contents of include/asm-*/{io,iomap}.h to migrate to.
