drivers: tee: improve sysfs interface by using sysfs_emit()
Replace scnprintf() with sysfs_emit() while formatting buffer that is
passed to userspace as per the recommendation in
Documentation/filesystems/sysfs.rst. sysfs _show() callbacks should use
sysfs_emit() or sysfs_emit_at() while returning values to the userspace.
This change does not impact functionality, but aligns with sysfs
interface usage guidelines for the tee driver.
