boards/stm32/nucleo-f429zi: update netnsh defconfig

This PR updates the netnsh defconfig for nucleo-f429zi board, as currently the board would not get ip.
Few changes comes with this PR:
* enabled CONFIG_NETINIT_NOMAC option.
* enabled CONFIG_NETINIT_DHCPC and CONFIG_NETUTILS_TELNETD as I wanted to get a telnet shell and did not care about ip handling
* disabled legacy pinmap and updated the board.h config to get the board to compile
