Adding maintainers.

Note: Armv7 is/was supported but was missing in the meson build system.

How compilation is looking? I guess there are tons of warnings?

It is better to add some guides together with this build support.

Do you have any plan on CI? 
I don't think DPDK Lab has Armv7 hardware to run tests.

Yes, we do have plans for CI for armv7, We are currently conducting
our testing with WPJ419 platform. I would like to note what all things
that should be taken into consideration for making CI support for armv7
related contributions.

Aso, we would like know how the testing for armv7 was done in older
DPDK releases, and what all things were considered, so that we can follow
the same.

[Ruifeng] I think basically we should have build for armv7. And in-tree unit tests are also preferred to run.
For traffic/performance tests, it is good to have.

Aso, we would like know how the testing for armv7 was done in older

[Ruifeng] As I know, there was no public CI for armv7 in older releases.
