[PATCH v4 2/2] ARM: DT: add power-off support to linkstation lsgl and kuroboxpro

[Roger Shimizu]

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
