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:

i2c: automatic device init by the BIOS
...
The BIOS can now initialize I2C peripherals during the boot.
The add_i2c_init_table method of the soc speficy parameters:
self.submodules.i2c = I2CMaster(pads)
self.add_i2c_init_table("i2c", i2c_addr=0x4c, table=it6263_i2c_hdmi_tx)
it6263_i2c_hdmi_tx = [
(0x05, 0x40),
(0x04, 0x3D),
(0x04, 0x1D)
...
The table is a list of tupple as (address, value).
