CPU parameters are now selectively exposed to the user:
./digilent_arty.py --cpu-type=vexriscv_smp --help will show VexRiscv-SMP parameters.
./digilent_arty.py --cpu-type=naxriscv --help will show NaxRiscv parameters.
This adds support for v2 of the board via a --board-version argument
and a way to select the FPGA speed grade via a --speed-grade argument.
Note that the speed grade now defaults to -1. QMTech confirmed that
V1 of the board were made in two batches, one with -1 and one with -2,
while V2 of the board is all -1. So -1 is the safer default.
This also fixes the inversion of j10 and j11 and a typo in the pin
definition of jp3

- main_ram mem_map is now directly used by add_sdram when origin is None.
- max_sdram_size/min_l2_data_width are no longer exposed as targets arguments this can
still be used enforced directly in the few cases it is useful.
Collect --with-ethernet/--with-etherbone, --with-spi-sdcard/--with-sdcard,
etc. into ArgumentParser.add_mutually_exclusive_group()s. That way, we
get pretty --help output, and appropriate error messages if somebody
tries to ask for something that doesn't make sense.
