targets: Change SoC/Software headers generation behaviour (Now only generated with --build).
...
Re-generating the SoC/Software headers was causing some un-expected behaviours for users not familiar
with the flow. For example doing a --load with a different configuration, was re-generating the Software
headers and messing up things when trying to run software on the SoC.

a611f035d6
targets: Move CRG before SoCCore init (More logical and simplify some specific reset schemes) and switch SoCCore to one line when possible.
...
Moving CRG simplify reset with NaxRiscv debug module and is in fact more logical.
Also do some minor updates/cosmetic changes while touching CRG/SoCCore.

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.

lambdaconcept_ecpix5: Add initial Video support at 640x480 (with Terminal/Framebuffer).
...
I2C intialization code adapted from https://github.com/ultraembedded/ecpix-5 .
Tested with:
- python3 -m litex_boards.targets.lambdaconcept_ecpix5 --cpu-type=firev --with-video-terminal --build --load
- python3 -m litex_boards.targets.lambdaconcept_ecpix5 --cpu-type=firev --with-video-framebuffer --build --load
