Andrew Jeffery f5808ac158 leds: gpio: Allow LED to retain state at shutdown ...

In some systems, such as Baseboard Management Controllers (BMCs), we
want to retain the state of LEDs across a reboot of the BMC (whilst the
host remains up). Implement support for the retain-state-shutdown
devicetree property in leds-gpio.
