Merge branch 'Ocelot-Felix-driver-cleanup' 

Vladimir Oltean says:

====================
Ocelot/Felix driver cleanup

Some of the code in the mscc felix and ocelot drivers was added while in
a bit of a hurry. Let's take a moment and put things in relative order.

First 3 patches are sparse warning fixes.

Patches 4-9 perform some further splitting between mscc_felix,
mscc_ocelot, and the common hardware library they share. Meaning that
some code is being moved from the library into just the mscc_ocelot
module.

Patches 10-12 refactor the naming conventions in the existing VCAP code
(for tc-flower offload), since we're going to be adding some more code
for VCAP IS1 (previous tentatives already submitted here:
https://patchwork.ozlabs.org/project/netdev/cover/20200602051828.5734-1-xiaoliang.yang_1@nxp.com/),
and that code would be confusing to read and maintain using current
naming conventions.

No functional modification is intended. I checked that the VCAP IS2 code
still works by applying a tc ingress filter with an EtherType key and
'drop' action.
