Removing ADDITIONAL_CONTROL_4 from the list of readable registers cause audio distortion.
This change was sent as a comment below the --- line when submitting commit 658bb297e393 ("ASoC: wm8962: Do not access WM8962_GPIO_BASE"), so it was not supposed to get merged.
Keep WM8962_ADDITIONAL_CONTROL_4 inside wm8962_readable_register() to fix the regression.
