Remove ultrasound settings from syspart_fixup

Updated ultrasound services settings do not require
writable system partition, therefore, the settings script
should be moved from syspart_fixup script to the
ultrasound post boot script.
The ultrasound post boot script is called each time,
in the late stage of the device start-up.
