adm1272 supports temperature reporting but it is disabled by default.

Tested:
ls temp1_*
temp1_crit           temp1_highest        temp1_max
temp1_crit_alarm     temp1_input          temp1_max_alarm

cat temp1_input
26642

Applied, after updating the affected driver in the subject line
(the change affects adm1272, but the driver is still the adm1275 driver).

Thanks,
Guenter
