The next move was to remove soc_core and only keep soc; so this is probably the right time to do
it in targets to avoid having to handle it later.

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.

Moving CRG simplify reset with NaxRiscv debug module and is in fact more logical.

tang_nano_4k: Review/Cleanup:
...
- Revert abstractions on clk_name/period: Too much abstraction to avoid duplications makes the code more difficult to read.
ex:
- When constraining clk27, frequency is already in the name.
- In the target, we want to know we are using clk27 as the main clk.
- We need a default sys_clk_freq for project only importing BaseSoC.
- Revert SPI Flash import (for consistency with other targets).
- Keep VexRiscv as default CPU since this target is able to run it and also for consistency with other targets.
