  7. drivers: timer: riscv_machine_timer: Add support for T-Head implement… 

    …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.

  11. scripts: runners: Add cvi-fiptool 

    The SOPHGO CVI series SoCs load the RTOS kernel for the 2nd core from a
`fip.bin` located in the main storage.

This commit introduced a convenient script for updating the `fip.bin` on
the external storage mounted to the host, with the newly built
`zephyr.bin`.

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