[ Upstream commit c6433083f5930fdf52ad47c8c0459719c810dc89 ]
The gmac2phy is integrated with the PHY within the SoC. Any properties related to this integration can be included in the .dtsi file, instead of having board dts files specify them separately.
Add the clock_in_out property to specify the direction of the PHY clock. This is the minimum required to have gmac2phy working on Linux. Other examples include assigned-clocks, assigned-clock-rates, and assigned-clock-parents properties, but the hardware default plus the implementation requesting the appropriate clock rate also works.
