Move vEdge 1000 to ToH and increase SFP port count in hwdata

Hello!

The device page for Cisco vEdge 1000 (https://openwrt.org/inbox/toh/cisco/vedge_1000) is ready to be moved out of inbox we think.

Also, for our hwdata we need to be able to select 8 SFP ports. Currently the max seems to be 4.

Ping @tmomas as per documentation and IRC recommendations.

Thanks!
