Align the board and driver prototype for board_interface_eth_init to avoid execution issue (the interface_type parameter is defined as int or phy_interface_t).
To have a generic weak function (it should be reused by other driver) I change the prototype to use directly udevice.
This prototype is added in netdev.h to allow compilation check and avoid warning when compiling with W=1 on file board/st/stm32mp1/stm32mp1.c
warning: no previous prototype for 'board_interface_eth_init'\ [-Wmissing-prototypes] int board_interface_eth_init(int interface_type, .... ^~~~~~~~~~~~~~~~~~~~~~~~

why can you just write a phy driver specific to this board and hook it to the eth driver in the dts ?
