board/BuR: drop devicetree loading and lcd setup for linux-targets
This patch drops the lcd-screen setup, the summary screen and getting mac-addresses based on a previous loaded device-tree for linux targets. Selecting those linux target is simple, since we have only the brppt1. In detail we do: - drop the common lcd-setup code which relys on a fdt_blob - drop the common dtb loading mechanism - drop the now obsolete CONFIG_USE_FDT from board header and whitelist.
