Patch "OMAP: hwmod/device: add omap_{device, hwmod}_get_mpu_rt_va"[1],
introduces omap_device_get_rt_va which is meant to be called
by drivers to retrieve the _mpu_rt_va, however this function
receives a pointer to an omap_device; since there is no
practical way for a driver to get this parameter without
fiddling with pdev and container_of macro, and omap_device code
already does this, it is better for it to handle this case.
Also moved header declaration to appear in the set of
functions to be used by drivers, as per the comment there.
