ASoC: Ensure the WM8962 oscillator and PLLs start up disabled
commit 2af8de8c39cf58e5a5e40a9d5d71332da98e6ba7 upstream. Since there is no current software control for these they would otherwise be left enabled, consuming power. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
