I would like to put all device in mt7623.dtsi with some device's
status is "disabled" and change its status in platform dtsi.
I would like to see all device in mt7623.dtsi because of its name. If
you move some device to platform dtsi, we would trace all platform
dtsi to find out how many device in mt7623. One day a new platform
enable different devices, you would reorganize all these platform
dtsi?

Chun-Kuang.
