build: Add initial OpenFPGA build backend with SOFA support and minimal blinky example.
...
OpenFPGA should be installed by following installation steps from https://github.com/lnis-uofu/OpenFPGA .
SOFA can be cloned from https://github.com/lnis-uofu/SOFA
Environment variables then need to be set:
export LITEX_ENV_OPENFPGA=/PATH_TO_OPENFPGA
export LITEX_ENV_OPENFPGA_SOFA=/PATH_TO_SOFA
A simple blinky test design is provided and can be built by executing blinky.py.

cpu: Add initial NaxRiscv support (From out of tree prototyping in litex_naxriscv_test).
...
- Supporting rv32ima for now.
- No interrupt support yet.
- AXI4 direct interfaces to LiteDRAM (fixed at 128-bit for now).
- AXI4-Lite interfaces to LiteX main bus.
- Pre-generated netlist used for now (need to allow customization/re-generation).
- Running in simulation with: litex_sim --cpu-type=naxriscv
- Running on hardware with: python3 -m litex_boards.targets.digilent_arty --cpu-type=naxriscv --build --load

cpu: Add initial NEORV32 support (From out of tree prototyping in litex_neorv32_test repo).

- Only configured for rv32i for now (need to create variants).
- I/DBus interfaces probably not optimal (latency).
- Converted from VHDL to Verilog through GHDL-Yosys-Synth (should also support direct VHDL use with toolchains supporting it).
- Interrupt not yet implemented.
- Running in simulation with litex_sim --cpu-type=neorv32.
- Running on Arty with: python3 -m litex_boards.targets.digilent_arty --cpu-type=neorv32 --build --load:
