Merge branch 'net-ipa-a-mix-of-cleanups'

Alex Elder says:

====================
net: ipa: a mix of cleanups

This series contains a set of cleanups done in preparation for a
more substantitive upcoming series that reworks how IPA registers
and their fields are defined.

The first eliminates about half of the possible GSI register
constant symbols by removing offset definitions that are not
currently required.

The next two mainly rearrange code for some common enumerated types.

The next one fixes two spots that reuse local variable names in
inner scopes when defining offsets.

The next adds some additional restrictions on the value held in a
register.

And the last one just fixes two field mask symbol names so they
adhere to the common naming convention.
