Thanks for the remarks. Please check my answers in-line below.

Fixed in the upcoming patchset.

Yes, looking at that file I realized that we also could add "crypto
device supported feature flags" for ARM. I created another commit in the
patchset (preceding the one with the documentation update for PMD).
The method of adding this flags is similar to what has been done earlier
for other PMDs and their features.
I used two names:
* NEON - which is an ARM component so we can use this name as a unique name.
* ARM_CE - for ARM cryptographic extensions. AFAIK there is no other
name for that.

Done with the new flags mentioned above as well. I'm sending another
patchset now and if you have some remarks to the new commits then let's
do another round :-).
