This adds an optional property "retain-state-shutdown" as requested by
Billy Tsai.

"Our platform is BMC that will use a PWM-FAN driver to control the fan
on the managed host. In our case, we do not want to stop the fan when
the BMC is reboot, which may cause the temperature of the managed host
not to be lowered."
I confirmed that it works properly.

Thank you very much for testing.
However, I plan to change this option to device attribute
(/sys/class/hwmon/hwmonX/retain-state-shutdown) instead of the device tree.
No, I won't acccept that.
