net: dsa: code re-organization

This pull request contains the first part of the patches required to implement
the grand plan detailed here:

http://www.spinics.net/lists/netdev/msg295942.html



These are mostly code re-organization and function bodies re-arrangement to
allow different callers of lower-level initialization functions for 'struct
dsa_switch' and 'struct dsa_switch_tree' to be later introduced.

There is no functional code change at this point.
