So the far, GXL SoCs were using the generic mmio register based mdio
multiplexer. This properly sets one of the glue register but the SoC
actually has 3 of those registers.
One of them sets the ID under which the internal phy will advertise
itself. If nothing sets this register before linux boots (like u-boot), the
internal phy path is broken.
To address this problem, a dedicated MDIO mux driver has been
introduced. Switch to this new driver.
