Add Elad Nachman as maintainer for Marvell Prestera Ethernet Switch driver.

Change Taras Chornyi mailbox to plvision.
This is a patch, so the description needs to explain why...
and who these people are. It would seem more natural if you,
Oleksandr and Yevhen were the maintainers.

Seriously, this is a community project please act the part.
The Marvell Prestera Switchdev Kernel Driver's focus and maintenance are
shifted from PLVision (Marvell Contractors) to the Marvell team in Israel.
In the last 12 months, the driver's development efforts have been shared
between the PLVision team and Elad Nachman from the Marvell Israel group.

Ah, damn, I was worried that's what you'd say :(

Elad Nachman is a veteran with over ten years of experience in Linux
kernel development.
He has made many Linux kernel contributions to several community
projects, including the Linux kernel, DPDK (KNI Linux Kernel driver) and
the DENT project.
Elad has done reviews and technical code contributions on Armada 3700,
Helping Pali Rohár, who is the maintainer of the Armada 3700 PCI
sub-system, as well as others in the Armada 3700 cpufreq sub-system.
In the last year and a half, Elad has internally dealt extensively with
the Marvell Prestera sub-system and has led various upstreaming
sub-projects related to the Prestera sub-system, Including Prestera
sub-system efforts related to the Marvell AC5/X SOC drivers upstreaming.
This included technical review and guidance on the technical aspects and
code content of the patches sent for review.
In addition, Elad is a member of the internal review group of code
before it applies as a PR.

I see 4 mentions of Elad Nachman in the entire git history.

The distinction between the kernel community and the corporate Linux
involvement is something I don't quite know how to verbalize.
And I don't know whether my perspective is shared by others.

Linux has taken over the world (at least the technical world) so having
Linux kernel exposure is common. But building a product based on Linux
which is then packaged and shipped to customers, in the usual corp
product development methodology, translates very poorly to developing
upstream. This is more true in networking that other parts of the
kernel, to my knowledge, because we attempt to build vendor-independent
abstractions.

While I do not mean to question Elad's expertise and capability as an
engineer/lead/manager, and very much appreciate Marvell's investment
in the upstream drivers for Prestera and in DENT -- I think the
community involvement is lacking. Short to medium term we should try to
find a way of improving this situation, we can clarify what we expect
from you and if you have ideas on how we can make the involvement**
easier - we'd love to hear them.

** community involvement ideas, less interested in how we can make the
"ship products" part easier, but you can share those too

Finally, do note the fact that I will continue to maintain/support this
driver, but I would like to have someone that I can share the effort with.

Understandable. I hope PLVision does not disappear form the picture.
We are really allergic to the "push the driver upstream and disengage"
or "throw it over the wall open source" model, if you will.

Unfortunately we only have one nuclear button for discouraging such
arrangements (git-rm), which will hopefully never be used.

To conclude, I think we should have a call first, and then decide
who the best choice for a maintainer is.

So we will drop this patch and create a new one with changing my email to PLVision one.
