2c3b1189fd hwmon: (adc128d818) Do proper sign extension 
data->temp[index] has type s16. Because of C's promotion rules,
(data->temp[index] << 7) >> 7 is exactly the same as
data->temp[index]. The intention was to use bit 8 as a sign bit, so do
that using the existing API.

7fe7381cbd hwmon: (adc128d818) Drop write support on inX_input attributes 
Writes into input registers doesn't make sense, even more so since
the writes actually ended up writing into the maximum limit registers.
Drop it.
