arndale_octa: Set EPLL as parent of AUDSS clockssamsung-lt-arndale_octa-2014.02
AUDSS clocks can have two parents, 24MHz crystal or the EPLL. By default
the crystal is set as the parent, but the rate is not sufficient for higher
frequency audio playback. Setting EPLL as the parent is required for
better audio playback.
