Subject: [PATCH] dts: Add ni-bluefinlc device tree

Device tree for Bluefin LC devices are for Low-cost
Ethernet cDAQ-9183 and cDAQ-9187.
The changes here is to update the model name, NIDEVCODE
and removal of dsa switch port 2 (sw1) since Bluefin LC
devices only have a single ethernet port. Otherwise, the
rest of the device tree remains the same as Bluefin.
