Pavel new maintainer of ARC port

[Pavel Kozlov]

Hi all,

I'm excited to introduce myself and become a part of the community. 

I'm a software engineer in Synopsys and member of a team working to enhance 
support for ARC CPUs in the GNU Linux ecosystem.

I would appreciate any guidance or advice on how I can get involved and 
contribute to the community. I'm always looking for opportunities to connect 
with other developers and learn from their experiences.

As a final step of setup, I've updated wiki and added myself as ARC 
maintainer. Also, thanks Carlos, for help with my setup.

Best regards,
Pavel Kozlov
