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.

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.
