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.

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.

digilent_arty/CRG: Add with_rst parameter to be able to easily disable rst.
...
On Arty, cpu_rst pin is connected to a button but also to USB-UART which also
resets the SoC when USB-UART is connected which is in some case not wanted.
with_rst provides an easy way to disable rst by setting it to False.

On the Digilent Arty, the SPI Flash's clk is connected to CCLK (that can be driven
through the STARTUPE2) but also to another generic IO that can be use to drive the
clock through DDR primitives.
