stm32f7:Allow the use of the Network Monitor via polling

Browse Source 
Not all boards have an interrupt line from the phy to
   the Soc. This commit allows the phy to be polled for
   link status.

   This may not work on all MAC/PHY combination that
   have mutually exclusive link management and operating
   modes. The STM32F7 and LAN8742AI do not have such a
   limitation.

Some boards may not have an interrupt connected to the PHY.
This option allows the network monitor to be used by polling the
the PHY for status.
