[BFN] Stop PMON before swss during warm reboot (#12658)

Why I did it
Stopping of pmon after swss and syncd causes some ERROR logs in syslog. Also, this affects teamd downtime.

How I did it
Adjust warmboot shutdown order in make file

How to verify it
Build SONiC image, deploy to the target device and check /etc/sonic/warm-reboot_order content.
