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 v4: Removed disabled drivers which actually build on arm32. Also tested the patchset with series 9609 which fixes underlying failures. v5: Changed the condition for running test-null.sh in ci. Re-uploaded after underlying fixes have been committed. v6: 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.
