ASoC: mid-x86: Use the soc-jack apis for jack type detection
This patch modifies the mfld_machine to use the new jack apis for adding the voltage zones for jack type detection. It also modifed TI sn95031 codec driver to use these new apis Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Harsha Priya <priya.harsha@intel.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
