Subject: [PATCH v3] hwmon:(adm1275) Enable adm1278 ADM1278_TEMP1_EN

The adm1278 temp attribute need it for openbmc platform .
This feature not enabled by default, so PMON_CONFIG needs to enable it.

v3:
----
fix invalid signed-off.
removed checkpath warnings.
write ADM1278_TEMP1_EN and ADM1278_VOUT_EN conf in single line operation.

v2:
----
add Signed-off-by.
removed ADM1278_TEMP1_EN check.

Signed-off-by: Manikandan Elumalai <manikandan.hcl.ers.epl@...il.com>
