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
