  Add support for aarch32 cross build in meson
and add aarch64 -> aarch32 cross build to Travis.

Aarch32 is an execution state that allows execution of 32-bit code on
armv8 machines. This execution state contains a superset of previous
armv7 32-bit instructions and features. Thus the aarch32 build is
distinct from arvm7 build.

Tested here:
[v6] https://travis-ci.com/github/jlinkes/dpdk/builds/179252628
[v7] https://travis-ci.com/github/jlinkes/dpdk/builds/179723067
[v8] https://travis-ci.com/github/jlinkes/dpdk/builds/181307330
[v9] https://travis-ci.com/github/jlinkes/dpdk/builds/181781602

Removed disabled drivers which actually build on arm32.
Also tested the patchset with series 9609 which fixes underlying

Changed the condition for running test-null.sh in ci.
Re-uploaded after underlying fixes have been committed.

Changed the condition for running test-null.sh again.
Reworked the patch to do aarch32 build instead of arvm7-a build.
Simplified meson build flags. Changed commit msgs.
Added 32b qualifier to .travis.yml.
Added a patch with fixes for bnxt.
Added a patch with cross compilation docs.

Rebased the patchset.

Removed Makefile additions from net/bnxt patch.

Changed ci test-null.sh condition, only run it if not
cross-compiling aarch64 nor aarch32.
Cleaned up docs.
