Got ls2 working on the Nexys Video!

UART only, no SPI, SDRAM, etc.

My steps, adapted from https://libre-soc.org/HDL_workflow/ls2/

cd ~/src/soc
make microwatt_external_core_bram_arty
cp external_core_top.v ../ls2
cd ../ls2
export PATH=/usr/local/nextpnr-xilinx/bin:$PATH
export XRAY_DIR=/usr/local/nextpnr-xilinx
python3 src/ls2.py nexys_video coldboot/coldboot.bin

Output on serial console:

 Soc signature: 00010001F00DAA55  Soc features: UART 
done

I'll push my local changes to ls2 once Nexys Video support is merged into
nmigen-boards.
