extcon: arizona: Add support for WM8998 and WM1814
This patch adds support for the WM8998 and WM1814 codecs. These use the same IP version as WM5110 but have different clamp control. Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
