A few models of Linkstation / KuroBox has micro-controller which
controls the power (as well as FAN, but not related here), while
others not. So remove the restart-poweroff driver in linkstation
common dtsi file, and specify the proper power driver in dts
of each device.
Devices need micro-controler to power-off:
- Linkstation LS-GL
- KuroBox Pro
Device continues using original restart-poweroff driver:
- Linkstation LS-WTGL
