net: ethernet: qualcomm: ppe: Demote from supported and fix maintainer addresses

Emails to the maintainer of Qualcomm PPE Ethernet driver (Luo Jie
<quic_luoj@quicinc.com>) bounce permanently (full mailbox), because the
"quicinc.com" addresses were deprecated for public work.  All Qualcomm
contributors are aware of that and were asked to fix their addresses.

Driver is not supported - in terms of how netdev understands supported
commitment - if maintainer does not care to receive the patches for its
code, so demote it to "maintained" to reflect true status.

Fix all occurences of Luo Jie email address to preferred and working
domain.
