Merge branch 'a-pile-of-sfc-deadcode'

Dr. David Alan Gilbert says:

====================
A pile of sfc deadcode

This is a collection of deadcode removal in the sfc
drivers;  the split is vaguely where I found them in
the tree, with some left over.

This has been build tested and booted on an x86 VM,
but I fon't have the hardware to test; however
it's all full function removal.
