ramips: reorganize NETGEAR sercomm boards

This re-organizes the device-tree files for the Sercomm-manufactured
NETGEAR routers. They are now split into two different base-boards,
from which the respective model is extended.

This partially reverts commit c7842ceaaa ("ramips: reorganize DTSI
files for Netgear R devices"), which introduced inheritance between two
completely unrelated base-boards.
