[PATCH 1/3] ppc32: Make platform devices being able to assign functions (update)

[PATCH 1/3] ppc32: Make platform devices being able to assign functions (update)

[Vitaly Bordug]

Implemented by  modification of the .name field of the platform device,
when PDs with the
same names are to be used within different drivers, as
<device_name> -> <device_name>:<function>
Corresponding drivers should change the .name in struct device_driver to
reflect upper of course.

Also helper platform_notify_map function added, making assignment of
board-specific platform_info more consistent and generic.

We should probably qualify the enum names a bit further for name  
space pollution.

I really dont like mixing the function "enet, usb, serial, ..." with  
the state enable/disabled.  We should separate these two items.
