targets: Simplify clock domains and remove useless reset_less.
...
rst was not directly assigned/used on reset_less clock domains, so reset_less
property was not really useful. With the changes on stream.CDC, having a rst
(Even fixed at 0) is now mandatory on clock domains involved in the CDC, so this
also fixes targets.

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.

- 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.
