ASoC: codecs: es8326: Fix DTS properties reading

Seems like properties parsing and reading was copy-pasted,
so "everest,interrupt-src" and "everest,interrupt-clk" are saved into
the es8326->jack_pol variable. This might lead to wrong settings
being saved into the reg 57 (ES8326_HP_DET).

Fix this by using proper variables while reading properties.
