With the new hwmon API, all attributes have to be created as groups.
Use sysfs_create_group and sysfs_remove_group instead of device_create_file
and device_remove_file to prepare for the new API.

Exception is the 'pec' attribute which will stay with the i2c device.

The hysteresis register is shared among both temperature sensors.
This means changing one also affects the other. To avoid confusion,
established way to express this is to make only the first instance writable
and keep all other instances as read-only. Otherwise users may be
confused that changing the second writable value also affects the first,
while it is more obvious that a writable value may affect a different
read-only value.
