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.

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.

v7:
Rebased the patchset.

v8:
Removed Makefile additions from net/bnxt patch.

v9:
Changed ci test-null.sh condition, only run it if not cross-compiling
aarch64 nor aarch32.
Cleaned up docs.

v10:
Fixed doc: add aarch32 build guidance commit message.

v11:
Rebase and fix scf and bnxt after rebase.

v12:
Dropped one superfluous net/bnxt patch.

v13:
Rebased and fixed net/virtio build by removing NEON for aarch32.

v14:
Fixed docs build.
