Subject: [PATCH 6.1.y 4/7] ASoC: codecs: ES8326: Change Volatile Reg function

From: Zhu Ning <zhuning0077@...il.com>

Commit f1230a27c14b4d05e1d6af02be55c617b53728a4 upstream.

The new calibration and headphone detection function
require reading new volatile registers. Add them in
the volatile register function.
