Joel Stanley b30dd0b5c6 test_cpu: Add NeoRV32 to tested CPUs 
With CI supporting GHDL to convert VHDL to Verilog the neorv32
simulation can be tested.

Fixes https://github.com/enjoy-digital/litex/issues/1320

Joel Stanley b0b57491bb test_cpu: Add Microwatt to tested CPUs 
Now that LiteX can convert from VHDL to Verilog using GHDL, and the
required dependencies are installed in the CI environment, start testing
Microwatt.

Joel Stanley b340b86975 test_cpu: Set number of verilator jobs 
By default verilator will be built with -j with no arguments, spawning
many processors. This causes large designs to failure in CI (probably
due to exhausting the memory of the build box):

 Error: Process completed with exit code 143.

Set the number of jobs to the number of CPUs in the system. This allows
designs such as Microwatt to build in CI.

Florent Kermarrec a57f0640cc soc/interconnect/csr: Add optional support fixed CSR mapping. 
By default, location is still automatically determined but it's now possible to
specific locations:

The following module:

class MyModule(Module, AutoCSR):
    def __init__(self):
        self.csr0 = CSRStorage()
        self.csr1 = CSRStorage(n=0)
        self.csr2 = CSRStorage(n=2)

built on a SoC with 32-bit CSR data-width will have the following CSR mapping:
- 0x00 : csr1
- 0x04 : csr0
- 0x08 : reserved
- 0x0c : csr2

- Split FSM in Main FSM/Xfer FSM to decouple Led data read from bit xfer and do read during xfer.
- Only keep optimization that are easily to understand.
- Default to new WS2812 revision (Since also works on old revision).
- Test 75/50/25MHz sys_clk_freq.

Florent Kermarrec 47b3c9bc08 soc/interconnect/packet: Remove last_be support in LiteX, specialized Packetizer/Depacketizer have been moved to LiteEth to simplify development and avoid eventual regresion on others cores. 
As seen during the last LiteEth developments, last_be data qualifier is not easy to handle correctly and should be replaced by a simpler data qualifier (similar to AXI's tkeep/tstrb). It will
be easier to do so by having a local copy of Packetizer/Depacketizer directly in LiteEth (still with last_be support) and work on the simpler data qualifier in LiteX (and test it on LitePCIe).
