Subject: [PATCH 4/5] of: module: Export of_uevent()

The content of of_uevent() is currently hardcoded in a driver that can
be compiled as a module. Nothing prevents of_uevent() to be exported to
modules, most of the other helpers in of_device.c actually are.The
reason why this helper was not exported is because it has been so far
only useful in drivers/base, which is built-in anyway.

With the idea of getting rid of the hardcoded implementation of
of_uevent() in other places in the kernel, let's export it to GPL
modules (very much like its cousins in the same file).
