hwmon: lis3: pm_runtime support
Add pm_runtime support to lis3 core driver.
Add pm_runtime support to lis3 i2c driver.
spi and hp_accel drivers are not yet supported. Old always
on functionality remains for those.
For sysfs there is 5 second delay before turning off the
chip to avoid long ramp up delay.
