hwmon: (adm1275) Add support for ADM1278
ADM1278 is mostly compatible to other chips of the same series. Besides the usual difference in coefficients, it supports a temperature sensor, and it can measure both input and output voltage at the same time. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
