The {read,write}s{b,w,l} operations are not defined by all architectures
and are being removed from the asm-generic/io.h interface.
This patch replaces the usage of these string functions in the musb
accessors with io{read,write}{8,16,32}_rep calls instead.

drivers/usb/musb/musb_io.h provides default implementations for
{read,write}s[bwl]() on most platforms, some of which will conflict soon
with platform-specific counterparts on m68k.
To avoid having to add more platform-specific checks to musb_io.h later,
make sure {read,write}s[bwl]() are always defined on m68k, and disable the
default implementations in musb_io.h on m68k, like is already done for
several other architectures.

On mips, we got:
drivers/usb/musb/musb_io.h:44: error: conflicting types for 'readsl'
arch/mips/include/asm/io.h:529: error: previous definition of 'readsl' was here
drivers/usb/musb/musb_io.h:46: error: conflicting types for 'readsw'
arch/mips/include/asm/io.h:528: error: previous definition of 'readsw' was here
drivers/usb/musb/musb_io.h:48: error: conflicting types for 'readsb'
so, should add !defined(CONFIG_MIPS) too.

Commit 1376d92f9 "usb: musb: allow musb and glue layers to be modules"
made the USB_MUSB_TUSB6010 option modular, but actually building
the driver as a module does not work, so various randconfig builds
actually fail. This changes all code that depends on the
option to also check for modular builds, and exports the necessary
symbols.

This will make things simpler when choosing which
glue layer to compile. It avoids a lot of magic
around the "default" Kconfig option and lets the
user choose what exactly s/he wants to compile.

For those archs which don't provide read/write friends we
provide our own implementation so musb driver won't break
compilation.
This is temporary fix until a better solution comes from
upstream. Idealy, <linux/io.h> would provide those calls
if the architecture did not provide them yet. In that case
being possible to remove all those stubs from musb_io.h

This patch adds support for MUSB and TUSB controllers
integrated into omap2430 and davinci. It also adds support
for external tusb6010 controller.
