Merge branch 'cxgb4-deadcode-removal'

Dr. David Alan Gilbert says:

====================
cxgb4: Deadcode removal

This is a bunch of deadcode removal in cxgb4.

It's all complete function removal rather than any actual change to
logic.

Build and boot tested, but I don't have the hardware to test
the actual card.
