	adm1272 and adm1278 supports temperature sampling. The
current way of enabling it requires the user manually unbind the device
from the driver, flip the temperature sampling control bit and then bind
the device back to the driver. It would be nice if we can control this in a
better way by reading the dt.

	Introducing device tree binding analog,temp1-enable. If the
flag is set, flip the temp1_en control bit on probing.

make dt_binding_check

ChangeLog v1->v2:
 - Rename adm1272-adm1278-temp1-en to analog-temperature1-enable

ChangeLog v2->v3:
 - Rename analog-temperature1-enable analog,temp1-enable
