Subject: of: device: make of_device_uevent_modalias() take a const device *

of_device_uevent_modalias() does not modify the device pointer passed to
it, so mark it constant.  In order to properly do this, a number of
busses need to have a modalias function added as they were attempting to
just point to of_device_uevent_modalias instead of their bus-specific
modalias function.  This is fine except if the prototype for a bus and
device type modalias function diverges and then problems could happen.  To
prevent all of that, just wrap the call to of_device_uevent_modalias()
directly for each bus and device type individually.
