side-switch: request bmc reboot to switch to new image
The final piece is to issue a BMC reboot so the system can get over to
the image with the highest priority.
Tested:
- Set running firmware priority to 1 and ran the application. Side
switch detection ran and BMC was rebooted. After the reboot, the
system automatically powered on and running image was priority 0.
