side-switch: check priority of running image
If the running image does not have the highest priority, then return a
side switch is needed
Tested:
- Running image has priority 0:
<6> Checking for side switch reboot
<6> Running firmware version path is /xyz/openbmc_project/software/74575136
<6> Running firmware version priority is 0
<6> Side switch not needed
- Running image has priority 1:
<6> Checking for side switch reboot
<6> Running firmware version path is /xyz/openbmc_project/software/74575136
<6> Running firmware version priority is 1
<6> Running image is at priority 1, execute side switch
- Running image has priority 1, alternate has priority 2
<6> Checking for side switch reboot
<6> Running firmware version path is /xyz/openbmc_project/software/ef4fd5ae
<6> Running firmware version priority is 1
<6> /xyz/openbmc_project/software/ef4fd5ae is the running image, skip
<6> Side switch not needed
- Running image is priority 3, alternate has priority 2
<6> Checking for side switch reboot
<6> Running firmware version path is /xyz/openbmc_project/software/ef4fd5ae
<6> Running firmware version priority is 3
<6> /xyz/openbmc_project/software/bf984b17 has a higher priority, 2, then running priority
