An upcoming netreg driver for uBlox modems will need to override the
probe method in order to set itself up, but for further functionality
the "generic" AT implementations are sufficient. The easiest way to do
this is to just set up a vtable with a custom probe implementation and
defer all other methods to the common/generic methods.
The problem is that the AT methods are not actually exported. This
generic AT functionality was not intended to be hooked directly into
other drivers.
This patch exports all the methods of the atmodem network-registration
driver implementation so that they can be used as generic/common
implementations for other drivers.
