This PR upgrades the TRNG module to the latest all-new neoTRNG V2. 🚀

  • much better random number quality
    • reworked architecture of entropy source
    • integrated post-processing for improved whitening
  • simulation mode: implements a pseudo-RNG (LFSRs) instead of the ring oscillators (comb. loops) to allow using the TRNG also in simulation - but of course with very bad (!!!) random number quality
    • added explicit flag to the TRNG's control register to check for simulation mode (bit 29: TRNG_CTRL_SIM_MODE)
