Merge branch 'sfc-even-more-code-refactoring'

Alex Maftei says:

====================
sfc: even more code refactoring

Splitting even more of the driver code into different files, which
will later be used in another driver for a new product.

This is a continuation to my previous patch series, and the one
before it.
There will be a stand-alone patch as well after this - after which
the refactoring will be concluded, for now.
====================
