…C (ESWIN EIC7700X SoC)

This PR adds support for the PINE64 StarPro64 64-bit RISC-V SBC,
based on ESWIN EIC7700X SoC. Most of the code was derived from NuttX
for Milk-V Duo S (SOPHGO SG2000). The modified code is explained here:
https://lupyuen.github.io/articles/starpro64#appendix-port-nuttx-to-starpro64
