[PATCH] of: make of_device_make_bus_id() static

[frowand . list]

From: Frank Rowand <frank.rowand@xxxxxxxxxxx>

of_device_make_bus_id() was changed to non-static by commit c66012253800
("of/device: Make of_device_make_bus_id() usable by other code") more than
6 years ago, but there are no users of it outside of platform.c.  Make the
function static again.
