For the Blackfin port, we can use much of the asm-generic/io.h header,
but we still need to declare some of our own versions of functions.
Like the __raw_read* and in/out "string" helpers.  So let people do
this easily for many of these funcs.

The asm-generic/iomap.h provides these functions already, but the
non-generic fallback defines do not.

atomic.h and io.h are based on the mn10300 architecture,
which is already pretty generic and can be used by
other architectures that do not have hardware support
for atomic operations or out-of-order I/O access.

Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.

This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305.  The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
