Add support for the maxlinear,rmii-refclk-out boolean property on port nodes to configure the RMII reference clock to be an output rather than an input. This property is only applicable for ports using RMII and allows the switch to provide the reference clock for RMII-connected PHYs instead of requiring an external clock source.
