ARM: dts: imx6qdl-sabresd: Pass reset-assert-us
According to the AR8031 datasheet: "When using crystal, clock is generated internally after the power is stable. In order to get reliable power-on-reset, it is recommended to keep asserting the reset low signal long enough (10 ms) to ensure the clock is stable and clock-to-reset (1 ms) requirement is satisfied." Pass the 'reset-assert-us' property to describe such requirement. While at it, use the 'reset-gpios' property inside the the mdio node instead of the deprecated usage of 'phy-reset-gpios'.
