====================
mlxsw: Preparations for restructuring

This patchset doesn't introduce any functional changes and merely meant
to make the code base more receptive for upcoming restructuring.

The first six patches mainly shuffle code in order to reduce the scope of
structs that shouldn't be defined in the main driver header. Most of them
will be later expanded, so it makes sense to correctly place them now.

The last patches mostly simplify bridge-related functions, so that they
could be more easily modified later on.
