Depends if the phy connection/assignment is really fixed or all boards
so far just happen to use the same one. If it is fixed and it's just a
matter of only one user can be active at a time, then yes, moving to the
SoC dtsi makes sense. The connection in the h/w is there, enabled or
not. Also, then the board is only dealing with "status" like many of the
blocks.
