net: stmmac: stm32: use PHY capability for TX clock stop
Whether the MII transmit clock can be stopped is primarily a property
of the PHY (there is a capability bit that should be checked first.)
Whether the MAC is capable of stopping the transmit clock is a separate
issue, but this is already handled by the core DesignWare MAC code.
Add the flag to allow the stmmac core to use the PHY capability.
