ARM: dts: imx6q-dhcom: Add ethernet VIO regulator

Browse Source 
Add VIO regulator that supplies multiple ethernet magnetics and
currently there is no upstream support for that in the networking,
so just keep the regulator enabled always to emulate what other
boards, which have this hard-wired, do. Until there is support.
