Subject: [PATCH] mount-tee-partition: add systemd unit to mount `persist`
 partition

Add a systemd .mount unit to ensure the `persist` partition is mounted at
/var/lib/tee. This directory is used by QTEE to store encrypted data, and
mounting it early in the boot process ensures the required filesystem is
available before services that depend on it start.
