pc87360: Check for error on sysfs files creation

pc87360: Check for error on sysfs files creation

Use sysfs_create_group() for 2 sensor-types which are chip-model
invariant, i.e. all-or-nothing attribute groups.
Other 2 groups vary too much due to configuration, etc, so we keep the
loops of device_create_file(), but now check their returns.
