[PATCH u-boot-marvell 06/12] arm: mvebu: turris_mox: Use show_board_info()

From: Marek Behún <marek.behun at nic.cz>

We are printing board information in last_stage_init(), but U-Boot has
dedicated function, show_board_info(), for this.

Move code which prints board information (board version, serial number,
module topology, ...) to show_board_info().
