[PATCH] of/device: Make of_device_make_bus_id() usable by other code.

[Grant Likely <grant.likely@secretlab.ca>]

The AMBA bus should also use of_device_make_bus_id() when populating device
out of device tree data.  This patch makes the function non-static, and
adds a suitable prototype in of_device.h
