The idea is to modify a .name field on a 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.

This is preliminary version, maybe some issues still need not be cleaned up, and there is no
"generic" platform_notify for board_specific code yet, but I'd like to see opinions concerning this stuff meantime.
