ramips: Add support for Netgear EX3800

The Netgear EX3800 is essentially an EX3700 with a mains output socket.

Both devices use the exact same firmware image (original firmware is named
EX3700-EX3800-version.chk).

This patch adds suport by renaming the EX3700 device to EX3700/EX3800 and
updating the necessary glue.
