Updates post_init_app.sh script, which installs

port-setup.sh script. port-setup.sh script,
will run devmem command for D5 interface, as soon as
D5 comes up on ACC, to enable connectivity.
Changes to post_init_app.sh to add extra logging.
Also changes to remove file removal(and sync), which was not required.
Per testing(several IMC reboots), changes(to run devmem command as
soon as D5 interface comes up on ACC) works fine in all-in-one
system. Changes also tested thro IMC reboots in our cluster,
and it works fine.
