From: John Harrison <John.C.Harrison at Intel.com>

The next GuC firmware release includes some significant backwards
breaking API changes. One such is that there is no longer an LRC
descriptor pool. A bunch of prep work for that change can be done in
advance - the descriptor pool was being used for things it shouldn't
really have been used for anyway.

v2: Extend commit message on 'better name' patch. Improve 'split
apart' patch to include some necessary re-arrangement that was in a
later patch and which introduced an unnecessary conditional in said
patch too. (review feedback from Daniele)
