Subject: [PATCH v3 02/12] dt-bindings: net: add new property st,ext-phyclk in documentation for stm32

Add property st,ext-phyclk to manage cases when PHY have no cristal/quartz
This property can be used with RMII phy without cristal 50Mhz and when we
want to select RCC clock instead of ETH_REF_CLK
Can be used also with RGMII phy with no cristal and we select RCC clock
instead of ETH_CLK125
This new property replace st,eth-clk-sel and st,eth-ref-clk-sel
