Allow the Jetson or CLI to request a security MCU reboot by having the main MCU drive EXP_MCU_RST_RQST_3V3 GPIO high for 100ms.

  • Add exp-mcu-rst-rqst-gpios to diamond_main DTS (gpio_exp1 pin 11)
  • Add handle_reboot_security_mcu handler in runner.c
  • Add orb reboot_sec CLI command (Diamond only)
