hwmon: (twl4030-madc) drop driver
This driver is no longer needed: * It has no mainline users * It has no DT support and OMAP is DT only * iio-hwmon can be used for madc, which also works with DT Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Acked-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
