This PR ports Zephyr to SOPHGO platforms, including 3 new SoCs and 3 boards:

Board Identifier SoC Link
Milk-V Duo milkv_duo CV1800B https://milkv.io/chips/cv1800b
Milk-V Duo S milkv_duos SG2000 https://milkv.io/chips/sg2000
Milk-V Duo 256M milkv_duo256m SG2002 https://milkv.io/chips/sg2002

The CV1800B is a member of the SOPHGO CV180X series. It's a multi-core RV64 SoC, consists with a 1GHz T-Head C906 RV64 big core running Linux, and a 700MHz C906 RV64 little core running RTOS.

The SG2000/SG2002 is a successor of CV1800B, belonging to the CV181x series. It features a 1GHz ARM Cortex-A53 big core, a 1GHz T-Head C906 RV64 big core (only one big core will be booted base on the selection of a BOOT GPIO), and a 700MHz C906 RV64 little core.

…ation

This commit adapts the existing RISC-V Machine Timer driver for the T-Head
C906 CPU:

* Although it's a RV64I CPU, the MTIMECMP register must be accessed as
  32-bit values.
* The value of the timer should be read using the `TIME` CSR, instead of
  the standard memory-mapped `MTIME` register.

`zephyr.bin`.

Path to the `fiptool.py` from the official SDK should be provided.
