I was able to make it work by patching the file. I know this might not be the desired fix so I won't send it as merge request:

.input_configured = appletb_input_configured,
#ifdef CONFIG_PM
.suspend = appletb_suspend,

.reset_resume = appletb_reset_resume,
#endif
};
With this change, the touchbar does work again back from Suspend. The only missing piece is the keyboard brightness which I don't think has to do with this driver, but with how the keyboard is brought back on resume (BCE driver perhaps?). Still researching that.
Edited:
I was able to bring the keyboard back-light as well by restarting upower on wake of sleep by adding the following file /lib/systemd/system-sleep/upower-onwake:
#!/bin/sh
# Restart UPower
case "$1" in

sleep 5
/usr/sbin/service upower restart
;;
esac
You could add a line as well to restore the backlight level. I chose not to.

Reproduce:
When opening, the Touchbar is not active. The following log is on /var/log/syslog:
