leds: provide helper to register "leds-gpio" devices
This function makes a deep copy of the platform data to allow it to live in init memory. For a kernel that supports several machines and so includes the definition for several leds-gpio devices this saves quite some memory because all but one definition can be free'd after boot. As the function is used by arch code it must be builtin and so cannot go into leds-gpio.c.
