MAINTAINERS: add Andrew Lunn as a co-maintainer of all networking drivers

Andrew has been a pillar of the community for as long as I remember.
Focusing on embedded networking, co-maintaining Ethernet PHYs and
DSA code, but also actively reviewing MAC and integrated NIC drivers.
Elevate Andrew to the status of co-maintainer of all netdev drivers.
