board/BuR/brxre1: convert do DM
This commit converts the brxre1 board to DM, for this we have todo following things: - add a devicetree-file for this board - drop all obsolete settings from board header-file - use dm_i2c_xxx calls for read/write to the resetcontroller - request gpios before operate them Serues-cc: trini@konsulko.com Signed-off-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>
