[PATCH] ppc32: Make platform devices being able to assign functions
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. Added ppc_sys_device_disable/enable function set, making it easier to disable all the inexistent/not utilized platform device way pdevs. By the check of the "disabled" bit in the config field of ppc_sys_specs, disabled platform devices will be either added/removed from the bus, or simply not registered on it, depending on the time when disable/enable call asserted. The default behaviour when nothing is disabled/enabled will be "all devices are enabled", which is the same as before. Also helper platform_notify_map function added, making assignment of board-specific platform_info more consistent and generic.
